WebV a r ( X) = σ 2. Var (X) = \sigma^2 V ar(X) = σ2, respectively. In R there exist the dnorm, pnorm and qnorm functions, which allows calculating the normal density, distribution and quantile function for a set of values. In addition, the rnorm function allows obtaining random observations that follow a normal distibution. WebMar 23, 2024 · We often use the rchisq () function to generate a list of n random values that follow a Chi-Square distribution with a given degrees of freedom. For example, we can use the following code to generate a list of 1,000 random values that follow a Chi-Square distribution with 5 degrees of freedom:
