How do you use a regression equation generated from one independent set of data to create predicted probabilities for another independent set of data with the same variables?  Essentially I would like to “save” the regression equation from my first dataset to predict for another dataset from a different year. Is this possible? Please excuse me if this information is on the website but I have been having difficulty while attempting to execute this particular task.

Thank you for your help
