two sample testcensored datamean lifetimeFor 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 non...

Inthis paper, we propose a statistical tool for testing equal means between two groupsin meta-analysis when the variances of the constituent studies are unreported, usingpivot inference based on the exact t-distribution and the generalized likelihood ratio.These are considered under a fixed effect ...
which says that the mean of the distribution of differences between sample means is equal to the difference between population means. For example, say that the mean test score of all 12-year-olds in a population is 34 and the mean of 10-year-olds is 25. If numerous samples were taken ...
When the scale of a dependent variable is not inherently meaningful, it is common to consider the difference between means in standardized units. That is, effect size is measured in terms of the number of standard deviations the means differ by. Two commonly used measures are Hedges' g and ...
Intervention analysis assesses the effect of an intervention on the response in studies where the response is observed before and after the intervention. The intervention might be a treatment of some sort, such as a drug, or a change in conditions. T
