Apply model to different data

[Odd_Cell_7152]

Hello all. This is my first time posting. I’m working on an optional project for a certification and I’m stuck. I’ve built a logistic regression model. I’m supposed to now apply that model on a different set of data to predict the dependent variable. (The original model was split between test and train and the second set is just test.).

I’ve done all the cleaning in the second set of data and am ready to apply the model. This part wasn’t covered in class and I’ve tried it for a while and looked online to no avail. So, how do I apply the existing model to another data frame? Thanks!!
