Interval Distribution Function
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 |
... |
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. |
