Checking assumptions of random part

Dear all,

I would like, if possible, some help to get me started in ML analysis. I have fitted a 2-level random slope model. There is a very useful slide summarising the various assumptions behind this model:

How can I test all these assumptions to see if the use of my model was warranted?

Thank you,

k.

Unfortunately these are axiomatic assumptions that allow the model to work but they are not directly testable; to my knowledge at least!
