comment What's an intuitive way to think about the determinant?
+1: I like this answer because there is a direct link to some application in physics: In special relativity we are talking of the conservation of space-time-volume, which means that the determinant of the transformation matrix is const. 1

comment generalized normal distribution with additional kurtosis parameter
this was really very helpful - Thank you. Do you know if there is also a log-pearson type vii distribution? I can't find any references in google...

comment generalized normal distribution with additional kurtosis parameter
I cannot follow: The other constraint is that when the third parameter is e.g. 3 (or 0) we are back to the normal distr.

comment generalized normal distribution with additional kurtosis parameter
@Raskolnikov: Ideally I want to let the parameters for mean and variance stay the same but having an additional parameter for kurtosis.

comment How can I obtain from a differential equation a stochastic version?
This could be interesting, so please extend your question (a little more flesh is needed!)
