Normal probability plot in r studio

WebThis is referred as normal distribution in statistics. R has four in built functions to generate normal distribution. They are described below. dnorm (x, mean, sd) pnorm (x, mean, sd) qnorm (p, mean, sd) rnorm (n, mean, sd) Following is the description of the parameters used in above functions −. x is a vector of numbers. WebNormal distribution has found applications in many fields. A continuous random variable X is said to have a normal distribution with parameters μ and σ 2 if its probability density function is given by. f ( x; μ, σ 2) = { 1 σ 2 π e − 1 2 σ 2 ( x − μ) 2, − ∞ < x < ∞, − ∞ < μ < ∞ , σ 2 > 0; 0, Otherwise. where e = 2. ...
