The Differences and Similarities Between Two-Sample T-Test and Paired T-Test
In clinical research, comparisons of the results from experimental and control groups are often encountered. The two-sample t-test (also called independent samples t-test) and the paired t-test are probably the most widely used tests in statistics for the comparison of mean values between two samples. However, confusion exists with regard to the use of the two test methods, resulting in their i...
متن کاملRESAMPLING STUDENT'S t-TYPE STATISTICS
The present paper establishes conditional and unconditional central limit theorems for various resampling procedures for the t-statistic. The results work under fairly general conditions and the underlying random variables need not to be independent. Specific examples are then the 're(n) (double) bootstrap out of k(n) observations, the Bayesian bootstrap and two-sample t-type permutation statis...
متن کاملSimulation and Bootstrapping for Teaching Statistics
Some key ideas in statistics and probability are hard for students including sampling distributions Com puter simulation lets students gain experience with and intuition for these concepts Bootstrapping can reinforce that learning and provide a way for stu dents and future practitioners to estimate sam pling distributions when they have data but do not know the underlying distribution Bootstrap...
متن کاملFir Statistics of Paired Galaxies
Much progress has been made in understanding the effects of interaction on galaxies (see reviews in this volume by Heckman and Kennicutt). Evidence for enhanced emission from galaxies in pairs firsi emerged in the radio (Sulentic 1976) and optical (Larson and Tinsley 1978) domains. Results in the FIR lagged behind until the advent of the IRAS satellite. The last five years have seen numerous FI...
متن کاملBootstrapping the Information Matrix Test
In this paper we provide considerable Monte Carlo evidence on the finite sample performance of several alternative forms of White’s [1982] IM test. Using linear regression and probit models, we extend the range of previous analysis in a manner that reveals new patterns in the behavior of the asymptotic version of the IM test – particularly with respect to curse of dimensionality effects. We als...
