8-42• Student- t DistributiontPD(: 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 pand 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 isassigned to Ans (ListAns when Lower and Upper are lists).InvTCD(: Returns the inverse Student-t cumulative distribution (Lower value) for the specifiedp value.Syntax: InvTCD(p,df [)]• A single value or a list can be specified for p . The Lower value is assigned to the xInv andAns variables (ListAns when p is a list).• 2 DistributionChiPD(: 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 pand Ans (ListAns when x is a list).ChiCD(: Returns the 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 assignedto variables p and Ans (ListAns when Lower and Upper are lists).InvChiCD(: Returns the inverse 2 cumulative distribution (Lower value) for the specified pvalue.Syntax: InvChiCD(p ,df [)]• A single value or a list can be specified for p . The Lower value is assigned to the xInv andAns variables (ListAns when p is a list).
