Normal Distribution

Distributions associated with the Normal Equation:

dnorm(x, μ , σ) Returns the probability density for value x.

pnorm(x, μ , σ) Returns the cumulative probability distribution for value x.

cnorm(x) Returns the cumulative probability distribution with mean 0 and variance 1.

qnorm(p, μ, σ) Returns the inverse cumulative probability distribution for probability p.

rnorm(m, μ, σ) Returns a vector of m random numbers having the normal distribution.

Arguments:

• x is a scalar or vector of real values.
• μ is a real mean.
• σ is a real standard deviation, greater than 0.
• p is an real probability between 0 and 1.
• m is an integer greater than 0.

Notes:

• For definitions of the functions, and information on generating random numbers, see the Density and Distribution definitions.
