I have an outcome variable which represents the number of aggravating clinical occurrences. For example if someone is obese, with high triglycerides and high blood pressure then the variable takes the value 3. I first thought to analyze this variable as a count variable using the poisson regression but I found out that it does not follow the poisson distrubution. The histogramm of this variable shows a very normal distributed variable; however, with seven possible values (0-6) it is not appropriate to use the linear regression. Then I thought that each level of the variable is worse than the previous (higher burden to health) and the ordinal regression may be suitable. What whould be the best regression to use with this variable as the dependet (outcome) variable?
