An S3 object which contains the point estimate
and test statistic after fitting a model to
a ScoreImputedData object.
modelThe model used to create the fit
methodThe method used for the fit
estimateA point estimate of the test statistic
varThe estimate for the variance of the test statistic
statisticThe test statistic given by estimate/sqrt(var)
The functions print.ScoreStat and as.vector.ScoreStat
have been included
The object contains the following:
The test statistic should be normally distributed and hence for the logrank test Z = (O_2 - E_2)/sqrt(V_2), i.e. the square root of the standard Chi squared statistic (with the appropriate sign)
