k Performing Distribution Calculations in a Program
• The following values are substituted whenever any of the arguments enclosed in brackets
([ ]) are omitted.
σ =1,  =0, tail=L (Left)
• For the calculation formula of each probability density function, see “Statistic Formula”
(page 6-69).
• Normal Distribution
NormPD(: Returns the normal probability density ( p value) for the specified data.
Syntax: NormPD(
x [, σ ,  )]
• A single value or a list can be specified for
x . Calculation result p is assigned to variables p
and Ans (ListAns when x is a list).
NormCD(: Returns the normal cumulative distribution (
p value) for the specified data.
Syntax: NormCD(Lower, Upper[,
σ ,  )]
• Single values or lists can be specified for Lower and Upper. Calculation results
p , ZLow, and
ZUp are assigned respectively to variables p , ZLow, and ZUp. Calculation result p also is
assigned to Ans (ListAns when Lower and Upper are lists).
InvNormCD(: Returns the inverse normal cumulative distribution (lower and/or upper value(s))
for the specified
p value.
Syntax: InvNormCD([ "L(or –1) or R(or 1) or C(or 0)" , ]
p [, σ ,  ])
tail (Left, Right, Central)
• A single value or a list can be specified for p . Calculation results are output in accordance
with the tail setting as described below.
tail = Left
The Upper value is assigned to variables
x 1InvN and Ans (ListAns when p is a list).
tail = Right
The Lower value is assigned to variables
x 1InvN and Ans (ListAns when p is a list).
tail = Central
The Lower and Upper values are assigned respectively to variables
x 1InvN and x 2InvN.
Lower only is assigned to Ans (ListAns when p is a list).
