WebbUse the probability distribution function normcdf as a function handle in the chi-square goodness-of-fit test (chi2gof). Test the null hypothesis that the sample data in the input vector x comes from a normal distribution with parameters µ and σ equal to the mean (mean) and standard deviation (std) of the sample data, respectively. WebbThe normal distribution is the probability density function defined by f ( x) = 1 σ 2 π ⋅ e ( x − μ) 2 − 2 σ 2 This results in a symmetrical curve like the one shown below. The surface areas under this curve give us the percentages -or probabilities- for any interval of values.
