Inverse Cumulative Normal Distribution
Command:
InvNorm
䡺
Description:
This command calculates the cumulative probability in a normal distribution
based on lower and upper limits.
Tail:Left
Upper boundary of
integration interval
α
= ?
Tail:Right
Lower boundary of
integration interval
α
= ?
Tail:Central
Upper and lower boundaries
of integration interval
α
= ?
β
= ?
Specify a probability and then use the above formulas to obtain the applicable
integration interval.
