Log-normal Distribution Real Statistics Using Excel

WebThe Pareto distribution has two parameters: a scale parameter m and a shape parameter alpha. The inverse function for the Pareto distribution is I(p) = m/(1-p)^(1/alpha). If you … WebFor fitting these estimates to data, consider measuring the goodness of fit for discriminating between two solutions when they are available. A $\chi^2$ statistic should do fine. This approach is illustrated in the following R code, which simulates data, performs the analysis, draws a histogram of the data, and overplots the solutions.
