NORMAL DISTRIBUTION in R 🔔 [dnorm, pnorm, qnorm and rnorm]

WebA cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. Where X is the random variable, and x is a specific value. WebDraw a graph of the density function. It looks like an isoceles right triangle with hypotenuse $2$ and apex at $(0,1)$ and very obviously has area $1$ (useful as a check on one's work.)
