Phat(2) should always be close to 2 (if it isn't that is a indication that chi-square is not a good fit) You can also use fitdist() pd = fitdist(R,'gamma'); For this example, I get: gamma distribution a = 2. Fit a normal distribution object to the data. All require the Statistics Toolbox. I was under the impression that fitdist was supposed to generate a probability plot, which would effectively normalize the data sets. The usual justification for using the normal distribution for modeling is the Central Limit theorem, which states (roughly) that the sum of independent samples from any distribution with finite mean and variance converges to the normal distribution as the sample size goes to infinity. The idea is to find the distribution that best fits a set of data. com The Distribution Fitter app interactively fits probability distributions to data imported from the MATLAB ® workspace.
