Description: An inverse normal distribution is a way to work backwards from a known probability to find an x-value. It is an informal term and doesn't refer to a particular probability distribution. Returns the value of the inverse normal distribution function for a specified value, mean, and standard deviation.
norminv(x, mean, stdev) Returns the value of the inverse normal distribution function for a specified value, mean, and standard deviation. Parameters: x: float, The input to the normal distribution function. mean: float, The mean (mu) of the normal distribution function stdev: float, The standard deviation (sigma) of the normal distribution function. Returns: float.
