Formula for invnorm
The inverse normal distribution is a type of probability distribution that is used to model the distribution of a random variable that is not normally distributed. The inverse normal distribution is used to calculate the probability of a particular value occurring, as well as the probability of a range of values.
The inverse normal (invnorm) function is a mathematical function that calculates the inverse of the normal distribution function.
Example of invnorm based on Formula
The inverse normal distribution is given by the formula:
invnorm(p) = μ + σ·erf-1(2p – 1)
where p is the probability, μ is the mean, σ is the standard deviation, and erf-1 is the inverse error function.
For example, if the probability is p = 0.95, the mean is μ = 0, and the standard deviation is σ = 1, then the inverse normal distribution is given by invnorm(0.95) = 0 + 1·erf-1(2(0.95) – 1) = 1.64.
