yes, the proportion of zeros in my data is very high, more than 90%.

comment How to calculate the mode of a probability distribution
@whubber, thank you for such a detail and useful explanation. However, where should I input my numeric parameters into? I have tried to input the value into last equation and when I define the dist, but it doesnt work.

comment How to calculate the mode of a probability distribution
my only problem with this command is that it takes ages in my Mathematica to run it with very large numeric parameters value. :(

comment How to calculate the mode of a probability distribution
will this work if I substitute the parameters with numerical values? Cause I tried to use your suggestion with alpha=1 and beta=2 but then it gives me this message:PolynomialGCD::lrgexp: Exponent is out of bounds for function PolynomialGCD.

hi, thanks for the suggestion! I will change my username soon :) I have tried use commonest but here is what I got: Commonest::arg1: The first argument is expected to be a list.

ah, so we are using the fact that var(x)=E(x^2)-E(X)^2 thanks!!
