ugeoPDf [Action][Distribution/Inv.Dist][Discrete][geoPDf]

Function: Returns the probability in a geometric distribution that the success will occur on a specified trial.

Syntax: geoPDf(x, pos [ ) ]

Calculation Result Output: prob

Example: To determine the geometric probability when x = 6, pos = 0.4

ugeoCDf [Action][Distribution/Inv.Dist][Discrete][geoCDf]

Function: Returns the cumulative probability in a geometric distribution that the success will occur between specified lower value and upper value.

Syntax: geoCDf(lower value, upper value, pos [ ) ]

Calculation Result Output: prob

Example: To determine the geometric probability when lower value = 2, upper value = 3, pos = 0.5

uinvGeoCDf [Action][Distribution/Inv.Dist][Inverse][invGeoCDf]

Function: Returns the minimum number of trials of a geometric cumulative probability distribution for specified values.

Syntax: invGeoCDf(prob, pos [ ) ]

Calculation Result Output: xInv, ￿xInv
