Question

do you have reason to believe there is omitted variable bias present? discuss statistic provided by Stata and perform overall significance test​

Answer 1

Answer:

You saw one method for finding confounding variables and detecting omitted variable bias in this post. If you include different combinations of independent variables in the model, and you see the coefficients changing, you're watching omitted variable bias in action!Intuitively, omitted variable bias occurs when the independent variable (the X) that we have included in our model picks up the effect of some other variable that we have omitted from the model. The reason for the bias is that we are attributing effects to X that should be attributed to the omitted variable.
