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.
