8-41• Logistic regression statistical calculationLogisticReg List 1, List 2y-axis data (YList)x-axis data (XList)k Performing Distribution Calculations in a Program• The following values are substituted whenever any of the arguments enclosed in brackets([ ]) are omitted.σ=1, =0, tail=L (Left)• For the calculation formula of each probability density function, see “Statistic Formula”(page 6-68).• Normal DistributionNormPD(: Returns the normal probability density (p value) for the specified data.Syntax: NormPD(x[,σ, )]• 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).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, andZUp are assigned respectively to variables p , ZLow, and ZUp. Calculation result p also isassigned 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 accordancewith the tail setting as described below.tail = LeftThe Upper value is assigned to variables x1InvN and Ans (ListAns when p is a list).tail = RightThe Lower value is assigned to variables x1InvN and Ans (ListAns when p is a list).tail = CentralThe Lower and Upper values are assigned respectively to variables x1InvN and x2InvN.Lower only is assigned to Ans (ListAns when p is a list).
