cureph.control {curephEM}

Ancillary arguments for controling cureph fits

Description

Assign the ancillary arguments for controling cureph fits

Usage

cureph.control(n.data,eps = 1e-09, toler.chol = .Machine$double.eps^0.75,
                 iter.max = 1000, toler.inf = eps^(1/3),
                 line.search=0.5,init.step = 1/n.data)

Arguments

n.data

Sample size of the data

eps

Iteration continues until the relative change in the log partial likelihood is less than eps. Must be positive.

toler.chol

Tolerance for detection of singularity during a Cholesky decomposion of the variance matrix, i.e., for detecting a redundant predictor variable.

iter.max

Maximum number of iterations to attempt for convergence.

toler.inf

Tolerance criteria for the warning message about a possible infinite coefficient value.

line.search

The scale of shrinkage in each Armijo line search step.

init.step

The initial size of step in Newton's method.

Details

line.search and init.step only matter when method = "BFGS-Newton".

Value

a list containing the values of each of the above constants
