Student-tDistribution

tPD(: Returns the Student-tprobability 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-tcumulative 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-tcumulative distribution (Lower value) for the specified

pvalue.

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).

Ƶ2 Distribution

ChiPD(: Returns the Ƶ2 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 Ƶ2 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 Ƶ2 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).
