• 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).
• 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 x Inv 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).
