The following values are substituted whenever any of the values enclosed in brackets ([ ]) are omitted.

Σ=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[, Σ, 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[, Σ, 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[,Σ, 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).
