StCDf

Function: Returns the cumulative probability of a Student-tdistribution between a lower bound and an upper bound.

Syntax: tCDf(lower value, upper value, df [ ) ]

Example: To determine the Student-tdistribution probability when lower value = 1.5, upper value = δ, df = 18

Menu Item: [Action][Distribution][tCDf]

For more information, see “Student-tCumulative Distribution” on page 7-11-7.

SinvTCDf

Function: Returns the lower bound value of a Student-tcumulative distribution probability for specified values.

Syntax: invTCDf(prob, df [ ) ]

Example: To determine the lower bound value when prob = 0.0754752, df = 18

Menu Item: [Action][Inv. Distribution][invTCDf]

For more information, see “Inverse Student-tCumulative Distribution” on page 7-11-8.
