Inverse Normal Cumulative Distribution
Menu: [Distribution]-[Inverse Normal CD]
Description: This command calculates the cumulative probability in a normal distribution
based on lower and upper bounds.
Tail:Left
Upper bound of
integration
α
= ?
Specify a probability and then use the above formulas to obtain the applicable
integration interval.
