Can you compare regression coefficients across two different variables?
I am using poisson’s regression model to estimate the count dependent variables. Join ResearchGate to ask questions, get input, and advance your work. Hi, suest can’t be used for IVregress. Any suggestions for comparing beta estimates for two IV regressions wherein only one variable (the instrument) is different, rest all are same. Thanks.
How are the two models of regression different?
The only difference between the two models is that they have different dependent variables: the first model is predicting DV1, while the second model is predicting DV2. All observations are from the same sample, so the regression coefficients are dependent.
What is the t value of regression coefficient Bf?
The T value is -6.52 and is significant, indicating that the regression coefficient Bf is significantly different from Bm . Let’s look at the parameter estimates to get a better understanding of what they mean and how they are interpreted.
Why is a regression coefficient bigger for men than for women?
Sometimes your research may predict that the size of a regression coefficient should be bigger for one group than for another. For example, you might believe that the regression coefficient of height predicting weight would be higher for men than for women.
How to compare a regression to a predictor?
To Compare Regression Coefficients, Include an Interaction Term. But if you want to compare the coefficients AND draw conclusions about their differences, you need a p-value for the difference. Luckily, this is easy to get. Simply include an interaction term between Sex (male/female) and any predictor whose coefficient you want to compare.
Can you compare the coefficients of two models?
The authors went on to compare the two models, and specifically compare the coefficients for the same predictors across the two models. Uh-oh. Can’t do that. If you’re just describing the values of the coefficients, fine. But if you want to compare the coefficients AND draw conclusions about their differences, you need a p-value for the difference.
