comment Can decimal numbers be considered “even” or “odd”?
@Ben: I appreciate your publicaly revealing your downvote, but I still feel you took a very subjective approach (probably based upon above comments?) to this answer because there so many answers which get voted up even though they do not appear to be in the spirit of seeking understanding. :)

comment What is the CDF for the following PDF of a cut-off log-normal distribution (in Matlab)?
The question is what is the CDF of the given distribution? If I know CDF then I can follow the rest of the steps...

Would it be correct if I find truncated normal random variables by generating the untruncated values and replacing those that are outside the limits. Then, finally use the truncated normal random variable, say y, as follow: r = rch * exp(y).?

comment How to express the traditional variogram for a non 2nd order stationary random function?
@Shai: Can you figure out from that expression why the difference between expected values at both points should be added?

@Shai: How would you back transform once you have pdf or cdf of log(W)?

comment Proof of upper-tail inequality for standard normal distribution
Also, the integral in first step is definition of CDF, but LHS i.e. P(X>x) is not CDF. How is that?

can you explain 2nd last step, when multiplying by (t/x)...how we get <= sign there?
