    partial differentiation variance truncated normal distribution

    Hi everyone,

    I have been working on the partial differentiation, but I have not been succesfull so far. Therefore I hoped someone here could help me solve it.

    The variance:



    What is the best way of partially differentiating w.r.t. this thing? I tried maple, but it gives an answer with which I can't work.

    I tried to copy paste it here, but that didn't work, nor did uploading as a picture..

    I hope someone has some good advice.

    Regards,
    Dirk

    I have no idea what you mean by "What is the best way of partially differentiating w.r.t. this thing?" You differentiate a function with respect to a variable. I suspect you meant to differentiate that "thing" wrt to a variable rather than "w.r.t. this thing". But what are the variables?

    Thanks for replying so quickly. Firstly, I made a mistake. I need to derive this formula. The variables are a, b and mu. So I am going to derive this following with respect to a, b and mu.



    Secondly, before you get to it, I would like try it myself again. Simply because this one is much easier to derive, I think.

    Again thanks for your quick reply. I do not want to get others to go through the trouble.
