WebNormal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Where: μ is the mean of samples in distribution or continuous location parameter. σ is the standard deviation or continuous scale parameter (‹ 0) 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.
