I have been working with the Moodle analytics models for the past few months. Currently, I am looking at the Student Risk of Dropping out model for my postgrad research. I have successfully trained it with one course but it didn't provide me with enough training data. I, therefore, uploaded a second course but when I try and train with it I get the "Not enough course activity between the start and the end of the course" error. I am not sure why this is because there is a lot of activity on the course. The course has 322 students, 66 different activities and spans over about 3 months.
I'm really not sure what the problem is, so any help would be really appreciated!
