Class exercise: Predicting income mobility in PSID

This repository contains data for a data science class exercise.<br><br><img alt=""><b>Students</b>: This exercise is about income mobility over three generations: grandparents (g1), parents (g2), and children (g3). Your task is to predict log income in generation 3 using data on log incomes in generations 1 and 2.<br><br>The data you will use are in for_students.zip.<br><ul><li>learning.csv contains 2,260 observations for which the outcome is recorded</li><li>holdout_public.csv contains 2,260 observations for which the outcome is NA</li></ul>Your task is to build a predictive model using learning.csv. Then, make predictions for the cases in holdout_public.csv.<br><br>Here are some details about the variables in the data: In each generation, we took each respondent's annual income over several surveys from age 30 to 45, adjusted to 2022 dollars, and took the average. We truncated the data to the range from $5,000 to $448,501.10, where the bottom code is arbitrary and the top code is what we believe to be the lowest PSID top code over the series (in 1978), converted to 2022 dollars. We merged the data together across generations using the PSID Family Identification Mapping System 3-generation prospective linkage file.<br><br>We are trusting the students to not open the instructor data, which contains the outcomes you are trying to predict. You could peek of course, but that would be no fun! We are trusting you not to peek.<br><br><b>Instructors</b>: For you, the file for_instructors.zip contains the true holdout outcomes in holdout_private.csv. You can use these to evaluate students' predictive performance (as long as you trust that they have not peeked).<br><br><b>For those replicating: </b>For you, the file for_replication.zip contains the directory structure and code that produced this exercise from raw files downloaded from the PSID.<br>
