Checks for enough observations

DESCRIPTION:

Checks that enough observations are available to fit a model.

USAGE:

censorReg.good.data(censor.codes, case.weights) 

REQUIRED ARGUMENTS:

censor.codes
vector of censor codes.
case.weights
vector of observation case weights.

VALUE:

T if the model may be fitted, F otherwise.

DETAILS:

No check is made that covariate parameters can be estimated. This is a "dumb" routine that merely checks that the sum of the case weights for the failures is greater than one. In fact, with more than one covariate, it still may not be possible to fit the model.

EXAMPLES:

This is an internal routine that would not normally be called by the user.
