    Infer confidence intervals of MLE using fisher information

    I have some count data that looks to be Poisson. After a goodness of fit, chi-squared test with p=0.5, I am comfortable saying it is from a Poisson distribution. I want to get confidence intervals for the mean/lambda. Can I use fishers information to find the variance of the MLE, and then use...

    I am working with some data that fits a gamma distribution and would like to get confidence intervals for the parameters alpha and beta. I have found the general form for the fisher information matrix of a gamma here and have the inverse to get the correlation matrix, but was wonder about how to...
