• Sinusoidal regression statistical calculation SinReg List 1, List 2 y-axis data (YList) x-axis data (XList) • Logistic regression statistical calculation LogisticReg List 1, List 2 y-axis data (YList) x-axis data (XList) I Performing Distribution Calculations in a Program (Not available on the fx-7400GII) • The following values are substituted whenever any of the values enclosed in brackets ([ ]) are omitted. S=1, ƫ=0, tail=L (Left) • For the calculation formula of each probability density function, see "Statistic Formula" (page 6-53). • Normal Distribution NormPD(: Returns the normal probability density (p value) for the specified data. Syntax: NormPD(x[, S, ƫ)] • 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). NormCD(: Returns the normal cumulative distribution (p value) for the specified data. Syntax: NormCD(Lower, Upper[, S, ƫ)] • Single values or lists can be specified for Lower and Upper. Calculation results p, ZLow, and ZUp are assigned respectively to variables p, ZLow, and ZUp. Calculation result p also is assigned 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[,S, ƫ]) tail (Left, Right, Central) • A single value or a list can be specified for p. Calculation results are output in accordance with the tail setting as described below. tail = Left The Upper value is assigned to variables x1InvN and Ans (ListAns when p is a list). tail = Right The Lower value is assigned to variables x1InvN and Ans (ListAns when p is a list). tail = Central The Lower and Upper values are assigned respectively to variables x1InvN and x2InvN. Lower only is assigned to Ans (ListAns when p is a list). 8-29
