comment Finding outliers without assuming normal distribution
What I also see sometimes is that researchers drop the top and bottom X % of their observations to reduce the influence of extreme cases. But I'm unsure whether I agree with it, it's quite arbitrary isn't it?

comment Panel data descriptives, plots and 'feel for the data'
Thanks for your suggestion. Now, this code is running for over half an hour now, is this because of the size of my data or is there a little mistake in the code? I already tried to look up some stuff about the code but I'm not that skilled with the STATA Syntax yet.

comment Summarizing five-point Likert scale
Exactly, the weights become less arbitrary and you can look at the factor loadings which question explains a lot of variation.

comment What are chunk tests?
For the sake of clarity, I think I was taught this as a "Partial F-test" where you test 2 or more variables for joint significance. Or whether a subset of variables in your model improves over the more restricted model (just like a likelihood ratio test). Am I correct?

comment How well does the normal distribution perform?
I think that's what the parameters (mean, stdev) determine. For example a low stdev (imposing a very skinny PDF) may impose a smaller likelihood of extreme values. Please others, correct me if I'm wrong.

comment Inconsistency in mixed-effects model estimation results (STATA and SPSS)
Thank you for the answer! So simple yet so frustrating. Especially because the labels Std. Err. and Std. Error correspond. Also, the fixed effects results are identical when you look at the numbers.
