Let me check the documentation... the description explicitly states `y`: \"Outcome column.\" Okay, that clarifies things.\n\nNow, a critical point... does the `wage` dataset actually have a column representing hourly wage? Or do I need to calculate it from existing columns? Or is there only a direct column name for the hourly wage?

The sample size of 935 observations, wage mean, hours mean, IQ mean, educ mean... that rings a bell. Yup, it's definitely the Wooldridge dataset. Specifically, it's the `WAGE2.RAW` dataset. In this dataset, I recall that `wage` is monthly earnings in 1980 dollars (or is it weekly?). And I need to recall the details of this specific Wooldridge dataset: `wage` is monthly earnings, `hours` is weekly hours, `IQ` is IQ score, `educ` is years of education, and `exper` is tenure.\n\nNow, the question is how to get the hourly wage and what format the regression model will accept. The key is to calculate hourly wage by dividing `wage` by `hours`. Does `infer.ols` accept this kind of expression, like `log(wage/hours)`? Or, will it only handle column names directly?

I'll utilize a try-except block, or just run a simple test with transformations, to observe the function's behavior. This empirical approach should quickly clarify the function's capabilities regarding formula integration and variable transformations without the tedium of exhaustive documentation review.

It's telling me the 'log(wage/hours)' column isn't there, which is a key indicator of where things are heading. The available columns are only these standard ones, and the error threw me off because it's not clear what is needed.\n\nAlright, time to re-read the prompt. It's asking for the percentage increase in *hourly* wage for each year of education, using linear regression, and to *only* consider 'wage', 'hours', and 'educ'. It's very specific about excluding other variables.\n\nNow the question is coming into focus. Does \"do not consider variables other than 'wage', 'hours', and 'educ'\" mean to regress `wage` on `educ` *and* `hours`? That interpretation seems to be correct, as I have to find the effect of education on wage.\n\nOkay, let's unpack that. If I regress `wage` on both `educ` and `hours`, what's the interpretation? It could mean `wage` is actually a total income (like monthly earnings = hourly wage * hours), the model needs to be formed. The question also specifies percentage increase. What if I regress `wage` on `educ` and `hours`?\n\nBut wait \u2013 why does the question specifically ask for a *percentage* increase? Linear regression spits out coefficients, not directly percentages. I need to figure out how to translate a coefficient into a percentage increase in hourly wage. It's a key question.\n\nTime to check what I have available.

I need to understand how education impacts hourly wage, and the key is this `core.scale_effect` function. It seems to translate model coefficients into interpretable effects: percent, standard deviations, etc. The description outlines the transformations: `log_points_to_percent`, `sd_units`, and `percent_of_baseline`.\n\nSpecifically, `percent_of_baseline` is grabbing my attention. It's defined as `100 * b / baseline`. This rings a bell.  In a standard linear model ($Y = \\beta_0 + \\beta_1 X + ...$), the percentage increase in $Y$ for a one-unit change in $X$ is indeed $\\frac{\\beta_1}{\\bar{Y}} \\times 100\\%$.  That *is* essentially `percent_of_baseline`!\n\nNow, the crucial question: what does $Y$ represent here? Is it \"hourly wage\" or just \"wage\"? I'm going back to the prompt and data description to be absolutely certain.\n\nAh, here's the dataset description. It specifies: \"The columns in this dataset include 'wage', representing the *total income*; 'hours', representing the *total hours worked*; and 'educ', representing the *years of education*\". Crucially, it uses the term \"total income\" and \"total hours\".\n\nSo, can I regress `wage` on `educ` and `hours`? My thinking now is that I *can* regress `wage` on `educ` and `hours`, since \"wage\" is the total income. Specifically, the data description is using the term \"total income\" when referring to \"wage\".\n\nTo actually test this, I'll use `infer.ols`. The dependent variable, `y`, will be \"wage\". The main independent variable, `x`, will be \"educ\". I'll consider two options: including \"hours\" as a control variable (i.e. `controls: [\"hours\"]`) *or* including \"hours\" as an independent variable (i.e. `x: [\"educ\", \"hours\"]`). This regression will tell me what I need to know.\n\n\n","tool_calls":[{"args":{"controls":["hours"],"dataset":"wage","x":["educ"],"y":"wage"},"llm_name":"infer__ols","tool_id":"infer.ols","vendor_id":"call_507177"}]},"response_id":"RsrQasihHYWHz7IPh6bQOQ","run_id":"20261015T124204Z-suite-qrdata_socsci-gemini-9c7e4b","seq":11,"task_id":"qrdata_socsci.353","timestamp":"2026-10-15T12:42:45.921897Z","usage":{"cached":18991,"input":23151,"output":52,"thoughts":502},"vendor":true}

The user wants a percentage increase in hourly wage per year of education, derived using linear regression, and crucially, they're explicitly limiting the analysis to \"wage,\" \"hours,\" and \"educ.\" That restriction on variables is the key. My immediate thought was, can I construct hourly wage directly? Unfortunately, there's no way to create a new column via data transformation. \n\nI checked all available tools to make sure. I also reread the prompt. The dataset is described as containing data on individuals' hourly wages. However, the variables in `wage.csv` include 'wage', 'hours', and 'educ'. At first, I was confused. Does \"wage\" in the dataset already represent the hourly wage?\n\nThen I reread the prompt again. It says that \"wage\" represents *total* income. The prompt is designed to emphasize the inclusion of \"hours\". The key here is the user specifically wrote \"do not consider variables other than 'wage', 'hours', and 'educ'.\" This is important because the dataset also contains other variables. If the user only wanted to regress \"wage\" on \"educ\", the prompt would say \"do not consider variables other than 'wage' and 'educ'\".\n\nSo, it's a regression of \"wage\" (total income) on \"educ\" (years of education) *and* \"hours\" (total hours worked). This is not a simple OLS. My focus shifts to the implication of controlling for hours. What does the inclusion of 'hours' in the regression equation mean?\n\nI remember the regression equation would look something like: Wage = \u03b2\u2080 + \u03b2\u2081Educ + \u03b2\u2082Hours + \u03b5. The user's question asks what the effect on hourly wage is. But what if we hold the hours constant? If $Wage = HourlyWage \\times Hours$, then holding $Hours$ fixed, the change in income with respect to education is $\\beta_1 = \\frac{\\partial Wage}{\\partial Educ}$.\n\nIf hours is fixed, the percentage change in hourly wage would be the same as the percentage change in total wage: holding hours constant, so the model must be:\n\n$\\ln(HourlyWage) = \\ln(Wage) - \\ln(Hours)$.\n\nHolding hours constant, $\\% \\Delta HourlyWage = \\% \\Delta Wage$!\n\nThe effect of education, holding hours constant, is then $\\beta_1$. The percentage increase in hourly wage (or wage), per year of education, is calculated as the coefficient on education divided by the mean wage. The mean cancels out the hourly variable. That is:\n\n$\\frac{\\beta_{educ}}{\\bar{Wage}} \\times 100\\%$!\n\nThe regression should return the relevant information. I recall that the regression that used \"educ\" and \"hours\" gave the same answer as the regression of \"wage\" on \"educ\" with \"hours\" as a control.

The `transform` parameter looks particularly important, allowing us to specify how the effect is scaled. It can be 'log_points_to_percent', 'sd_units', or 'percent_of_baseline'.\n\nNow, let's put it to the test. I think I'll start with `transform='percent_of_baseline'`.  For the `coefficient`, I'll use the figure reference 'call_f86a6591:coef.educ', I know that should be available. And for the `baseline` value, let's grab 957.945.

That's essentially 6.36%, rounded to the nearest hundredth of a percent. I immediately consider the implication: is that a meaningful result in the context of the model? Now, my mind immediately jumps to a potential scaling issue. What if we stripped out the hours dimension and checked the `core.scale_effect` on the educational coefficient? A quick peek at `call_6afedbe4:coef.educ` should do the trick. Just need to verify that.

And it needs to be to the nearest hundredth of a percent, so I'll keep that in mind.\n\nNow, let's get into the heart of it.  I need to provide an estimate for the percentage increase in hourly wage per year of education. The data involves 'wage', 'hours', and 'educ', and I'm using linear regression, which has been performed.\n\nLet me break down the calculations. It seems like I have two scenarios to consider: with and without controlling for hours worked.\n\nWhen I *do* control for `hours`:\n\n*   The coefficient on `educ` is 60.8777 (with a standard error of 6.16757 and a 95% confidence interval [48.7738, 72.9817]).\n*   This translates to a percentage of 6.35503% relative to the mean wage (957.945), which I'll round to 6.36% (with a 95% confidence interval [5.0915%, 7.61857%]).\n\nWithout controlling for `hours`:\n\n*   The coefficient on `educ` is 60.2143 (se: 6.15696, 95% CI [48.1312, 72.2974]).\n*   This translates to a percentage of 6.28578%, which is 6.29% (95% CI [5.02442%, 7.54713%]).\n\nNow, there's a little nagging thought \u2013 hourly wage is W/H. I need to make sure I'm using the mean of the ratio of wage to hours, or the ratio of means.  It turns out that I can't directly compute the mean of $W/H$ from the provided summary stats, but it's important to keep that in mind.\n\nOkay, let's see, has `percent_of_baseline` done the right scaling? I see the baseline mean of wage is 957.945, and with the regression I have:  `coef.educ` is 60.8777. So, the `effect` comes out as 6.35503%, which rounds to 6.36%.\n\nNow, before I present the answer, I need to check the caveats:\n\n*   This is observational data, and OLS estimates are vulnerable to omitted variable bias (things like ability, family background, school quality, or measurement error).  So, this is a conditional association, not necessarily a causal effect.\n*   The linear specification models an additive dollar increase per year of education.  The percentage return is at the sample mean.\n\nLet me make sure all my figure references and numbers are consistent:\n\n*   `call_f86a6591:coef.educ`: 60.8777\n*   `call_f86a6591:coef.hours`: -2.21664\n*   `call_af8e73fd:effect`: 6.35503\n*   `call_6afedbe4:coef.educ`: 60.2143\n*   `call_78bcdb6e:effect`: 6.28578\n\nAll seems correct and backed by the tools! I'm confident.\n\n\n","tool_calls":[{"args":{"answer":"Based on a linear regression of total wage on years of education (`educ`) controlling for hours worked (`hours`), each additional year of education is associated with an expected increase in wage of 60.8777 (SE = 6.16757; 95% CI: [48.7738, 72.9817]).
