search for: chance_to_present_symptom

...month in range <0..30> (where 30 is daily and zero for never) and independent variables: X1 - sex - category {M,F} X2 - age - linear value X3 - type of work {administrative, manual, ...} ... Which model is "the best" for my problem: to describe weight of factors in equation "chance_to_present_symptom ~ variables": Y~X1+X2+X3 Y is not linear value with normal distribution. Y describe something like chance of to have symptom. I can't use linear regression, but something like logistic regression. Logistic is only for two (or more) Y value which is categorised not linear. Thank for any...
