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).
• Student- t Distribution
tPD(: Returns the Student- t probability density ( p value) for the specified data.
Syntax: tPD(
x , df [)]
• 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).
tCD(: Returns the Student-
t cumulative distribution ( p value) for the specified data.
Syntax: tCD(Lower,Upper,
df [)]
• Single values or lists can be specified for Lower and Upper. Calculation results
p , tLow,
and tUp are assigned respectively to variables
p , tLow, and tUp. Calculation result p also is
assigned to Ans (ListAns when Lower and Upper are lists).
InvTCD(: Returns the inverse Student-
t cumulative distribution (Lower value) for the specified
p value.
Syntax: InvTCD(
p , df [)]
• A single value or a list can be specified for
p . The Lower value is assigned to the x Inv and
Ans variables (ListAns when p is a list).
• 
2
Distribution
ChiPD(: Returns the 
2
probability density ( p value) for the specified data.
Syntax: ChiPD(
x , df [)]
• 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).
