Description Usage Arguments Value References Examples
A function used to produce the results of three type of statistical inference methods for testing cumulative incidence functions at fixed time point.
1 |
time |
The followed up time for testing data. |
status |
The status indicator, should be coded as 0= censored, 1= event of interest, 2= all other competing events. |
group |
The group indicator for comparison, and the elements of this vector should take either 0 or 1. Normally, 0= control group, 1= treatment group. |
timepoint |
The fixed time point for testing. |
type |
Four type of statistical inference methods. "1" is related to Gaynor variance, "2" is related to Aalen variance. The default is set to type=1. |
method |
Containing 5 transformation of statistical inference methods: line, log, cloglog, arcsin-square, and logist. See more details in references. |
est0 |
The estimation of survival rates at the fixed timepoint for control group. |
var0 |
The estimation of variances at the fixed timepoint for control group. |
est1 |
The estimation of survival rates at the fixed timepoint for treatment group. |
var1 |
The estimation of variances at the fixed timepoint for treatment group. |
statistic |
The statistics of corresponding methods. |
Pvalue |
The test P value of corresponding methods. |
