Allright, then i didn't fully understand the video. Good for pointing that out. After looking for different options i found out that due to over-dispersion the negative binonimal distribution is best to use as an alternative to the Poisson regression. Do you agree? With a scatterplot for the...

Thanks for your response hlsmith, When i follow this video , and perform a One-Sample Kolmogorov-Smirnov Test. I find that the Asymp. Sig. (2-tailed)= 0,000, which means, according to the video, that the model doesn't follow a Poisson distribution. This means that the assumptions for performing...

Thanks for your reply. Yes i should have explained it better. With a follow-up i meant repeated measures, each variable was measured twice. The data will be obtained through a questionnaire and the first measurements will start coming month. The plan is to have at least 200 participants. Do i...
