What is the pnorm() Function in R - R-Lang
WebbThe normal distribution is defined by the following probability density function, where μ is the population mean and σ 2 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).It can be graphed as … http://web.mit.edu/15.423/test/notes/pdf/Text_Ch_5_Measuring_Risk_Introduction.pdf WebbJust to check on this, the R code for the standard normal CDF is pnorm, and the statement pnorm (0.8416212) returns 0.8 exactly.
