I am concerned with a r.v. Y=X ^ -1 where X ~ N(0,1). What is the pdf of Y and what is the mean, variance? Any one, please?
 

complicated pdf?

Mean is calculated by substituting x*pdf(x) in the interval to f(x)*pdf(x); similar approach for the variance: just substitute the RV index with the function on the RV index.

Click to expand...

But when you evaluate the integral for mean what happens? Is it zero or infinity or undefined? Can you try that for me?

Sorry pmonon, the mechanics of evaluating integrals was never my stronger side. Anyhow, N(0,1) means normal distribution or uniform distribution for the original RV?
