NORMSDIST
Calculates values for the cumulative distribution function of a normal distribution.
Syntax:
NORMSDIST(x)
- The standard normal distribution is a normal distribution with mean μ = 0 and standard deviation σ = 1.
- NORMSDIST calculates the cumulative distribution function of the standard normal distribution.
- It is equivalent to NORMDIST(x; 0; 1; 1).
Example:
NORMSDIST(0)
- returns 0.5. The standard normal distribution curve is centred on 0, hence half of the curve is below 0.
NORMDIST(0; 0; 1; 1)
- also returns 0.5.
See also:
NORMDIST, NORMSINV, NORMINV, PHI
Issues:
- The forthcoming international standard ODFF regards this as a legacy function, preferring NORMDIST.
