a_qnorm {vacuum}

Returns the typical value from a unit-normal distribution

Description

Returns the typical value from a unit-normal distribution for the ith ordered observation in an n-sized sample.

This is a helper function for FUNOP, which uses the output of this function as the denominator for its slope calculation.

Usage

a_qnorm(i, n)

Arguments

i

Non-zero index of an array

n

Non-zero length of the array

Value

Quantile of i from a unit-normal distribution
