I am working on a paper that has three outcome variables: BMI, risky sexual behaviour, and access to healthcare. BMI is categorised into thin, normal and obese. Risky sexual behaviour is categorised into no risk, low risk, and high risk. Access to health care has three categories, low, moderate and high. The categories are ordered, so, I deceided to use ordered logistic regression instead of multinomial regression. With ologit, I need to test if proprotionality assumption holds. I need help on how to download and use brant test.
