WebThe normal distribution is defined by the following probability density function, where μ is the population mean and σ2 is the variance . If a random variable X follows the normal distribution, then we write: In particular, the normal distribution with μ = 0 and σ = 1 is called the standard normal distribution, and is denoted as N(0,1). WebA normal probability plot of the residuals is a scatter plot with the theoretical percentiles of the normal distribution on the x axis and the sample percentiles of the residuals on the y axis, for example: Note that the relationship between the theoretical percentiles and the sample percentiles is approximately linear.
