Distribution
Definition of Terms
Lower : lower boundary
Upper : upper boundary
σ: standard deviation (σ > 0)
∝ : mean
Input Example:
NormCD 0.5,0.8,1.23,0.56
Calculation Result Output
prob : normal distribution probability p
z Low : standardized lower limit z value
z Up : standardized upper limit z value
Inverse Cumulative Normal Distribution
Command: InvNorm
Description: This command calculates the cumulative probability in a normal distribution based on lower and upper limits.
Tail:Left | Tail:Right | Tail:Central |
Upper boundary of | Lower boundary of | Upper and lower boundaries |
integration interval | integration interval | of integration interval |
α = ? | α = ? | α = ? β = ? |
Specify a probability and then use the above formulas to obtain the applicable integration interval.
Command Syntax
“Tail setting”, Area value, σ value, ∝ value
Definition of Terms
Tail setting: probability value tail specification (L (Left), R (Right), C (Central))
Area : probability value (0 <Area <1)
σ: standard deviation (σ > 0)
∝ : mean
Input Example:
InvNorm “L”,0.35,1.2,0.3
