NormDist - script and chart function
NormDist() returns the cumulative normal distribution for the specified mean and standard deviation. If mean = 0 and standard_dev = 1, the function returns the standard normal distribution.
Syntax:
NORMDIST(value, [mean], [standard_dev], [cumulative])
Return data type: number
Arguments:
Argument | Description |
---|---|
value | The value at which you want to evaluate the distribution. |
mean |
Optional value stating the arithmetic mean for the distribution. If you do not state this argument, the default value is 0. |
standard_dev |
Optional positive value stating the standard deviation of the distribution. If you do not state this argument, the default value is 1. |
cumulative |
You can optionally select to use a standard normal distribution or a cumulative distribution. 0 = standard normal distribution 1 = cumulative distribution (default) |
This function is related to the NormInv 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.
