I am trying to do a study of deaths due to malaria in order to find the best way to predict how dangerous this disease is.
I don't have a strong background in statistics, I am an auto-learner building my knowledge using online courses.
First, I collected the data this way :
Statistics(gender, age, ..) | Number_Death
As far as I know, my options are
GLM with a Binomial distribution: for predicting if this dangerous or not. In this case, I labelled the predictor to be 0 (for no death), 1 for one or more cases.
GLM with a Poisson distribution: for predicting the number of events based on the predictor.
Now, I am confused. For what purposes would we use a GLM with Gaussian distribution, a GLM with a Gaussian and a log link function, or a GLM with a Gamma distribution?
