Class: Normal  - X-Ref

distribution($value, $mean, $stdDev, $cumulative)   X-Ref
NORMDIST.

Returns the normal distribution for the specified mean and standard deviation. This
function has a very wide range of applications in statistics, including hypothesis
testing.

param: mixed $value Float value for which we want the probability
param: mixed $mean Mean value as a float
param: mixed $stdDev Standard Deviation as a float
param: mixed $cumulative Boolean value indicating if we want the cdf (true) or the pdf (false)
return: array|float|string The result, or a string containing an error

inverse($probability, $mean, $stdDev)   X-Ref
NORMINV.

Returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.

param: mixed $probability Float probability for which we want the value
param: mixed $mean Mean Value as a float
param: mixed $stdDev Standard Deviation as a float
