Tail Probability for t-distribution

Description

Tail Probability for t-distribution

Usage

iscamtprob(xval, df, direction, xval2 = NULL, verbose = TRUE)

Arguments

xval	observed value.
df	degrees of freedom.
direction	direction for probability calculation, "above" or "below"; if "outside" or "between" are used, a second larger observation, xval2 must be specified
xval2	second observation value.
verbose	Logical, defaults to TRUE. Set to FALSE to suppress messages

Value

The tail probability in the specified direction using the given arguments.

Examples

iscamtprob(xval = -2.05, df = 10, direction = "below")
iscamtprob(xval = 1.80, df = 20, direction = "above")
iscamtprob(xval = -2, xval2 = 2, df = 15, direction = "between")
iscamtprob(xval = -2.5, xval2 = 2.5, df = 25, direction = "outside")
