Compute the derivative of the PDF of a StableDistribution

Hi to everyone,

I would like to evaluate somehow the derivative of the PDF of a StableDistribution in Mathematica 10, namely

D[PDF[StableDistribution[0, 1.88134, 0.736172, -0.0601042, 0.101782], x],x]

numerically or by other means. I would like to plot it (say, in the interval {x,-8,8}) alone and combined with other functions that I know how to plot and evaluate.

Thanks in advance!

Thanks Udo,

Your solution works very well for me and it is more elegant; it serves as well for other cases under study without specific changes. I tried ND before but I did not know that a package had to be loaded...

Thanks again, and best wishes.

I have found a way to do it, by means of the simple idea of approximating a derivative by the quotient of increments when the increment of the variable x is very small. It works very well and the graph is quite good.

Thanks to everyone anyway.
