• Poisson Distribution

PoissonPD(: Returns the Poisson probability (p value) for the specified data.

Syntax: PoissonPD(x, [)]

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).

PoissonCD(: Returns the Poisson cumulative distribution (p value) for the specified data.

Syntax: PoissonCD([Lower,] Upper, [)]

Single values or lists can be specified for Lower and Upper. Calculation result p is assigned to variables p and Ans (or ListAns).

InvPoissonCD(: Returns the inverse Poisson cumulative distribution for the specified data.

Syntax: InvPoissonCD(p, [)]

A single value or a list can be specified for p. The calculation result X value is assigned to the xInv and Ans variables (ListAns when p is a list).

Geometric Distribution

GeoPD(: Returns the geometric probability (p value) for the specified data.

Syntax: GeoPD(x, P[)]

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).

GeoCD(: Returns the geometric cumulative distribution (p value) for the specified data.

Syntax: GeoCD([Lower,] Upper,P[)]

Single values or lists can be specified for Lower and Upper. Calculation result p is assigned to variables p and Ans (or ListAns).

InvGeoCD(: Returns the inverse geometric cumulative distribution for the specified data.

Syntax: InvGeoCD(p,P[)]

A single value or a list can be specified for p. The calculation result is assigned to the xInv and Ans variables (ListAns when p is a list).
