 Apr9 awarded Editor Apr9 comment Which probability distribution does my discrete variable approximate?Sorry, my last comment does not make sense because I applied the formula of variance of a binomial distribution to a geometric distribution. Apr9 revised Which probability distribution does my discrete variable approximate?added 196 characters in body Apr9 comment Which probability distribution does my discrete variable approximate?@DilipSarwate Thanks, but I am limited in choosing the distribution for this variable (for further analysis), and geometric distribution is not one of these. Or do you mean fitting this will help me choose between extraBin and NegBin? Because this gives p=0.3. And applying your formula gives a variance of 1.31. Apr9 comment Which probability distribution does my discrete variable approximate?@DilipSarwate I believe the software calculated with an assumption of normal distribution. I will look into my mistake there. @ leonbloy I asked it at stats but I did not get a conclusive response. So I believe more in depth math knowledge is required.

But isn't that using the solution to get to the solution? I mean, could I do it without making use of the derivations yet in step 1. Jan11 asked Derivation of equalities from odds ratio
