prepare.n1 {valorate} | R Documentation |
This method estimates the log-rank distribution for a minor size group equal to n1.
prepare.n1(vro, n1)
vro |
the valorate object. |
n1 |
a numerical value (perhaps integer) of the size of the survival group. |
This method actually estimates the log-rank distribution for a minor size group equal to n1. This method is internally called by all functions to first check and/or compute the log-rank distribution of n1. It is not intended to be used by final users unless it is intended to prepare the VALORATE object before p-value calculations (perhaps in separated threds or jobs and saving/restoring the object).
The updated valorate object. This is a S4 method operating an object, so the valorate object specified in argument will be updated with the estimations of the distribution of the log-rank for n1 subjects.
