Documentation/How Tos/Calc: PHI function

PHI

Calculates values for a standard normal distribution.

Syntax:

PHI(x)

The standard normal distribution is a normal distribution with mean μ = 0 and standard deviation σ = 1.

PHI calculates the probability density function of the standard normal distribution; in other words it returns NORMDIST(x; 0; 1; 0).

Example:

PHI(0.5)

returns approximately 0.35206.

NORMDIST(0.5; 0; 1; 0)

returns approximately 0.35206.
