discrete random variables

  1. S

    Dependent variable from ratio counts. That's discrete? If yes, which test for low Ns?

    Hi all, I have a rather specific question, I somehow don't seem to be able to find the answer to. So I work on biological tissue, where I count the number of cells that have been 'touched' by a particular axon. Meaning that my counts are ratios-percentages: dependent variable: 'percentages of...

    Combining two dependant discrete random variables

    Hi, I’m looking for a way to combine two discrete random variables (which I have as probability distributions). The combination should be the product (or other operation) of the two variables. This would be easy if they were independent, but they’re not. There is a known correlation between...

    Poisson distribution - goodness of fit

    I want to test goodness of fit for poisson distribution for a very large data set (~millions of records). Can anybody suggest a method? All the methods that are available are for small data sets.

    Comparing probability distributions over discrete random variables

    Hi guys Sorry if the post is not in the right place but I am new here. I am comparing the performance of two monte carlo methods. The results I got are the marginals for the same set of random variables. Lets say for example: First Method Second Method X1 0.62...
