To Obtain Trustworthy Regression Resultsįollow the below steps to obtain a trustworthy regression result.This p-value will help you to determine whether the relationship you observe in the sample also works with the larger population or not. When you have a p-value less than 0.05 then the independent variable is statistically significant. After doing this, you must look at the regression coefficients and the p values. In regression analysis, you must first fit and verify that you have a good model. So, omitting a variable causes the model to be uncontrolled and the result is biased toward the variable which is not present in the model. Studies show that a relevant variable can produce misleading results. How to Control Other Variables in Regression: In regression analysis, you hold the other independent variables constant by including them in your model. This process allows you to know more about the role of each variable without considering the other variables. To do this, you need to minimize the confounding variables. We can say that it strategically controls all the variables within the model.ĭefinition of Controlling a Variable: When the regression analysis is done, we must isolate the role of each variable.
