comment Probability distribution for a function of a random variable
Thats right, its not independent. X's distribution is a function of parameter t (which is known). And t has a known probability distribution. Question remains: what is then distribution of X knowing distribution of t?

I mean that distribution for parameter t is independent of distribution for X ^^

comment Plot randomly oriented gaussian kernel
I am writting with Python. It does not matter I think. BTW it is multivariate gaussian, so that I have a hint I should add a cross x-y term in exponential. however I would appreciate more precise explanation or pointer to some reference

Thanks for answer. In first expression for f, x is not in definition domain, so that f is smooth on its open definition domain, ]-infty,0[U]0,infty[ ; in second expression for f, it is smooth on both domains ]-infty,0[ and ]0,infty[ separated by the value where thing under sqrt is zero --> so this verifies the mentionned 'rule' (I am on the interpreter side, who seeks for domains for running optimization routines in which derivatives are needed)
