For the two-sample problem with censored data, a difference of means test is formulated. We use simulation to compare this test to the popular log-rank test under various distributions. It is seen to perfom better than the logrank test for some nonproportional hazard alternatives, while ...

Test method. Use thetwo-sample t-testto determine whether the difference between means found in the sample is significantly different from the hypothesized difference between means. Analyze Sample Data Using sample data, find the standard error, degrees of freedom, test statistic, and the P-value...

This means that, in the absence of treatment, the trends in both the treatment and control groups would have followed a parallel path over time. Section 2: Implementing the Difference-in-Differences Modelin R 2.1 Data Preparation: First, acquire and import the dataset into R. Ensure that the...
