Regression Analysis: Interpreting Stata Output
Table includes coefficients for two out of the three categories for race. Because Stata chose White as the base category, our interpretation of the other two coefficients for race will be made in comparison to White. Let’s report the marginal effects.Related Article: Publication Style Regression Output in Statamargin, dydx(*)The marginal effect for males relative to females is still similar to our previous regression. As compared to females, males have 0.05 higher probability of having high blood pressure.Black people, controlling for gender, have a 0.65 lower probability of having high blood pressure as compared to white people. Hispanic people have a 0.084 lower probability of having high blood pressure than white people while controlling for gender.All three marginal effects are statistically significant.Interaction Terms in RegressionsIn examples similar to the above, it is often relevant to study how two variables interact and affect the outcome variable together. For example, it is very likely that gender and age interact together to affect the probability of high blood pressure.We can ask Stata to display the interaction effects of two variables by writing one or two hash (#) signs between them. If we specify only one hashtag, Stata will output only the interaction effects. If we add two hashtags, Stata will report both the main effect for each variable and their interaction effect.Let’s look at the main effects and the interaction effect of gender and the age group that a person belongs to. We use the allbaselevels option once again to report which categories (and pairs of categories) were dropped by Stata..probit hbp male##age_group, allbaselevelsThe main effect and interaction effects for the 15-19 age group and for females were dropped. The marginal effects are as follows:margin male##age_groupThis table suggests that if everyone in the data would be treated as a male, their probability of having high blood pressure would be 0.065, while for females, this probability would be lower at 0.018.If everyone in the data were treated as belonging to the 15-19 age group, their probability of having high blood pressure would be 0.0195 but as the age group increases, this probability also increases to Stata - extract regression output for 3500 regressions run in a loop. 0.

2025-04-17Covers all the new Stata developments relevant tomicroeconometrics that appeared since the the last edition in 2010. Forexample, readers will find entire new chapters on treatment effects,duration models, spatial autoregressive models, lasso, and Bayesiananalysis. But the authors didn't stop there. They also addeddiscussions of the most recent microeconometric methods that have beencontributed by the Stata community.The first volume introduces foundational microeconometric methods,including linear and nonlinear methods for cross-sectional data andlinear panel data with and without endogeneity as well as overviews ofhypothesis and model-specification tests. Beyond this, it teachesbootstrap and simulation methods, quantile regression, finite mixturemodels, and nonparametric regression. It also includes an introductionto basic Stata concepts and programming and to Mata for matrixprogramming and basic optimization.The second volume builds on methods introduced in the first volume andwalks readers through a wide range of more advanced methods useful ineconomic research. It starts with an introduction to nonlinearoptimization methods and then delves into binary outcome methods withand without endogeneity; tobit and selection model estimates with andwithout endogeneity; choice model estimation; count data with andwithout endogeneity for conditional means and count data for conditionalquantiles; survival data; nonlinear panel-data methods with and withoutendogeneity; exogenous and endogenous treatment effects; spatial datamodeling; semiparametric regression; lasso for prediction and inference;and Bayesian econometrics.With its encyclopedic coverage of modern econometric methods paired withmany worked examples that demonstrate how to implement these methods inStata, "Microeconometrics Using Stata, Second Edition" is a text thatreaders will come back to over and over for each new project or analysisthey face. It is an essential reference for applied researchers andthose taking microeconometrics courses.About the authorsColin Cameron is a professor of economics at the University of California–Davis, where he teaches econometrics at undergraduate and graduate levels, as well as an undergraduate course in health economics. He has given short courses in Europe, Australia, Asia, and South America. His research interests are in microeconometrics, especially in robust inference for regression with clustered errors. He is currently an associate editor of the Stata Journal. Pravin K.
