Student's s-statistic

نویسنده

چکیده

Student's t-statistic is a data-based linear transformation of an average. This paper proposes an extension i) to more general estimates including m.l.e.'s and M-estimates, and ii) to nonlinear transformations, so that the variance of the estimate is approximately constant. The expansion of the statistic and its properties are derived using basic procedures for the symbolic computation of asymptotic expansions.

Saddlepoint Approximation for Student ’ S T - Statistic with No Moment Conditions

A saddlepoint approximation of the Student's t-statistic was derived by Daniels and Young [Biometrika 78 (1991) 169–179] under the very stringent exponential moment condition that requires that the underlying density function go down at least as fast as a Normal density in the tails. This is a severe restriction on the approxima-tion's applicability. In this paper we show that this strong expon...

A Small-Sample Correction for Testing for gth-Order Serial Correlation with Arti cial Regressions

Monte Carlo experiments establish that the usual \t-statistic" used for testing for rst-order serial correlation with arti cial regressions is far from being distributed as a Student's t in small samples. Rather, it is badly biased in both mean and variance and results in grossly misleading tests of hypotheses when treated as a Student's t. Simply computed corrections for the mean and variance ...

A note on using permutation-based false discovery rate estimates to compare different analysis methods for microarray data

MOTIVATION False discovery rate (FDR) is defined as the expected percentage of false positives among all the claimed positives. In practice, with the true FDR unknown, an estimated FDR can serve as a criterion to evaluate the performance of various statistical methods under the condition that the estimated FDR approximates the true FDR well, or at least, it does not improperly favor or disfavor...

t -Tests, F -Tests and Otsu's Methods for Image Thresholding

Otsu's binarization method is one of the most popular image-thresholding methods; Student's t -test is one of the most widely-used statistical tests to compare two groups. This paper aims to stress the equivalence between Otsu's binarization method and the search for an optimal threshold that provides the largest absolute Student's t-statistic. It is then naturally demonstrated that the extensi...

A Case Study on Choosing Normalization Methods and Test Statistics for Two-Channel Microarray Data

DNA microarray analysis is a biological technology which permits the whole genome to be monitored simultaneously on a single slide. Microarray technology not only opens an exciting research area for biologists, but also provides significant new challenges to statisticians. Two very common questions in the analysis of microarray data are, first, should we normalize arrays to remove potential sys...
