idf: Interval Distribution Function

Description

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

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.

Value

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

Details

When left and right endpoints are equal, the intervals reduce to points. print.idf prints an object of class idf as a three-coumn matrix.
