What type of regression should I use I have a dataset that gives data on infertitlity and causes. The dataset is mainly 0,1 to represent "yes" and "no". However, some fields have "Sometimes", "Often" which would be represented by -1 or 2. I've only learnt how to do categorical data i.e. 1,0 and Numberical data. So my question is since there are more options other than 1 and 0, which type of regression do I use? Logistic regression or Linear regression?
Using  Logistic regression or Linear regression depend on the dependent variable(DV). Based on your question, I believe that your DV will be infertitlity(Yes/No) so you should use logistic regression because linear regression is for the continuous variables(e.g:exam score) and logistic regression is for categorical variables(e.g.L Yes/NO)
