idf: Interval Distribution Function

In npsurv: Nonparametric Survival Analysis

Description

Class idf can be used to store a distribution function defined on a set of intervals. There are several functions associated with the class.

Usage

idf(left, right, p)
## S3 method for class 'idf'
print(x, ...)

Arguments

left, right	left and right endpoints of intervals on which the distribution function is defined.
p	probabilities allocated to the intervals. Probability values will be normalized inside the function.
x	an object of class idf.
...	other arguments for printing.

Details

idf creates an object of class idf. An idf object stores a distribution function defined on a set of intervals.

When left and right endpoints are identical, the intervals just represent exact points.

print.idf prints an object of class idf as a three-coumn matrix.

Value

left, right	left and right endpoints of intervals on which the distribution function is defined.
p	probabilities allocated to the intervals.
