NormInv - script and chart function
NormInv() returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.
Syntax:
NORMINV(prob, mean, standard_dev)
Return data type: number
Arguments:
Argument | Description |
---|---|
prob | A probability associated with the normal distribution. It must be a number between 0 and 1. |
mean | A value stating the arithmetic mean for the distribution. |
standard_dev | A positive value stating the standard deviation of the distribution. |
This function
is related to the NormDist function in
the following way:
If prob = NORMDIST(value, m,
sd), then NORMINV(prob, m, sd) = value
Limitations:
All arguments must be numeric, else NULL will be returned.
