Fit the normal distribution
WebApr 8, 2024 · I am trying to determine the goodness of fit of a probability distribution. The following code finds the parameters of a gamma distribution that fits the data, which is sampled from a normal distribution. How do you determine the goodness of fit, such as the p value and the sum of squared errors? WebMar 6, 2024 · The two main parameters of a (normal) distribution are the mean and standard deviation. The parameters determine the shape and probabilities of the distribution. The shape of the distribution changes as the parameter values change. 1. Mean The mean is used by researchers as a measure of central tendency.
