WebOct 13, 2016 · The package vcd comes with the goodfit() function which essentially does exactly what you ask for: fit the model by ML and then visualize observed and fitted frequencies. By default, a square-root scale is adopted to better bring out departures at lower expected frequencies. Also, by default, the bars are hanging from the curve to … Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon. The aim of distribution fitting is to predict the probability or to forecast the frequency of occurrence of the magnitude of the phenomenon in a certain interval. There are many probability distributions (see list of probability distributions) of which some can b…
