• 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 xInv and
Ans variables (ListAns when
p is a list).
• Ƶ
2
Distribution
ChiPD(: Returns the Ƶ
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).
ChiCD(: Returns the
Ƶ
2
cumulative distribution (p value) for the specified data.
Syntax: ChiCD(Lower,Upper,
df [)]
• Single values or lists can be specified for Lower and Upper. Calculation result
p is assigned
to variables p and Ans (ListAns when Lower and Upper are lists).
InvChiCD(: Returns the inverse
Ƶ
2
cumulative distribution (Lower value) for the specified p
value.
Syntax: InvChiCD(
p,df [)]
• A single value or a list can be specified for
p. The Lower value is assigned to the xInv and
Ans variables (ListAns when p is a list).
• F Distribution
FPD(: Returns the F probability density (p value) for the specified data.
Syntax: FPD(
x,ndf,ddf [)]
• 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).
FCD(:Returns the
F cumulative distribution (p value) for the specified data.
Syntax: FCD(Lower,Upper,
ndf,ddf [)]
• Single values or lists can be specified for Lower and Upper. Calculation result
p is assigned
to variables p and Ans (ListAns when Lower and Upper are lists).
