Calculates the maximum likelihood estimates with Interval Censoring Using the EM Algorithm.
weibull.ic(X, start=c(1,1), maxits=10000, eps=1E-5)
X |
a numeric matrix (n x 2) of observations. |
start |
a starting value. |
maxits |
the maximum number of iterations. |
eps |
the desired accuracy (convergence tolerance). |
The expectation-maximization(EM) algorithm is used for estimating the parameters with interval-censored data.
