Hello everyone I am analyzing data from an experiment with 10 treatments, 4 blocks repeated in 13 moments. One of the variables has zero values ​​until the fifth or sixth moment. After that, the measurements start to appear. I thought about adjusting some type of model considering a threshold parameter, perhaps with a gamma or exponential distribution, and comparing the treatments at the moments. I would like to know if it would be possible to adjust it like this or, better yet, a model with repeated measurements? How would you consider the beginning of the data? Like to hear suggestions.   Thank you in advance ... View more

Hi all I have a case-control design with binary response repeated in 3 moments. I would like to get some reference about how analyse the main effects as well as obtain OR or RR. I guess in this case Rr is more appropriate due to longitudinal aspect of the design.  I´m using glimmix but I´m not sure if this is effective to get all information an how to interpret the results.   Thanks in advance for any help José Eduardo ...
