Hello,
I have a stepwise regression and I have the following results when I save the model in the database :
What does that mean ? Indeed, I have several coefficients for the same modality in a variable and it makes me "match". For example the modality "39" has 2 coefficients, "1" and "-1"
What are the "match"?
Thank you for your help
Here is a sample file I want to make a logistic regression model to predict the "Quality" variable representing the quality of cheeses.
In the example, I only put 6 variables but actually there is much more.
Before making my logistic regression model, I wanted to make a stepwise regression in order to select the best variables to integrate them into my model
However, I don't understand why it separates me into several groups the Variable Year, Month and Week
Indeed, these can not be continuous digital variables, they are in the correct format: ordinal digital
Thanks for your help
