The A matrix is an n by k matrix of zeros and ones, where each row represents one of n failure times,
and each column represents
a possible interval for the nonparametric maximum likelihood estimate (NPMLE).
The function Aintmap creates an A matrix and associated intmap
from left and right intervals (L and R) which may not may not include the boundary
of the interval (using Lin or Rin).
The matrix intmap denotes the intervals of the potential jumps in the distribution of the
NPMLE,
and its attribute LRin denotes whether to include each of the intervals
or not. Called by icfit.
Usage
Aintmap(L,R,Lin=NULL,Rin=NULL)
Arguments
L
numeric vector of left endpoints of censoring interval
R
numeric vector of right endpoints of censoring interval
Lin
logical vector, should L be included in the interval? (see details)
Rin
logical vector, should R be included in the interval? (see details)
