Grouping variables in a data frame
Hi All,
I have a data frame as follow:
user_id time age location gender
.....
and I learn a logistic regression to learn the weights (glm with family= (link = logit))), my response value is either zero or one. I would like to group the users based on user_id and time and see the y values and predicted y values at the same time. Or plot them some how. Is there any way to somehow group them
