The second contrast compares the regression coefficients of the young vs. middle aged and seniors. Vrije Universiteit Amsterdam * http://www.stata.com/support/faqs/res/findit.html I already built two separate regression model for each city and one single regression model with dummy variables (cityA=1, cityB=0). So, let's say I have two regressions: ... new to Stata and with my uni being closed due to the coronavirus pandemic I am unable to get lessons on how to operate Stata. ... X2 and X3 are jointly different between Group 1 and Group 2 by means of an F test. Testing the equality of multiple coefficients in R. Ask Question Asked 4 years, 6 months ago. For example, you could use multiple regression to determine if exam anxiety can be predicted based on coursework mark, revision time, lecture attendance and IQ score (i.e., the dependent variable would be "exam anxiety", and the four independent variables would be "course… The syntax is a bit awkward with multiple treatments – it only does corrections for the first regressor in each equation, so if you want to test for multiple treatments, you have to repeat the regression and change the order in which treatments are listed. LM-Test. name] _b[coefficientname] = [equation2 name] _b[coefficientname]".

This test will have 2 df because it compares three regression coefficients. st: test of coefficients of the same regression equation. The standard approach would be to take one of the three tests. The intercept term in a regression table tells us the average expected value for the response variable when all of the predictor variables are equal to zero. st: RE: comparing regression coefficients across models ----------------------------------------- Dismiss Join GitHub today. Frequently there are other more interesting tests though, and this is one I’ve come across often — testing whether two coefficients are equal to one another. Below, we show how you can perform two such tests using the contrasta statement in proc glm. Related. >> What test should I run, and what STATA commands should I type to test whether one coefficient of a regression is larger or smaller than another coefficient? From See the (substantively nonsensical) example below: r(100); Boelelaan 1081 Date suest regprice regmpg Comparing equality of coefficients in different regressions ... Hey guys, I'm trying to do a basic test of whether two coefficients are different in different regressions. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Is there any method/creteria to standardize regression coefficients coming from different regressions. Would be grateful for pointers.
