Karl Pearson’s meta-analysis revisited
نویسنده
چکیده
This paper revisits a meta-analysis method proposed by Pearson (1934) and first used by David (1933). It was thought to be inadmissible, for over fifty years, dating back to a paper of Birnbaum (1954). It turns out that the method Birnbaum analyzed is not the one that Pearson proposed. We show that Pearson’s proposal is admissible. Because it is admissible it has better power than the standard test of Fisher (1932) at some alternatives, worse power at others. Pearson’s method has the advantage when all or most of the nonzero parameters share the same sign. Pearson’s test has proved useful in a genomic setting, screening for age-related genes. This paper also presents an FFT based method for getting hard upper and lower bounds on the CDF of a sum of nonnegative random variables.

Karl Pearson’s Meta-analysis Revisited by Art
This paper revisits a meta-analysis method proposed by Pearson [Biometrika 26 (1934) 425–442] and first used by David [Biometrika 26 (1934) 1–11]. It was thought to be inadmissible for over fifty years, dating back to a paper of Birnbaum [J. Amer. Statist. Assoc. 49 (1954) 559–574]. It turns out that the method Birnbaum analyzed is not the one that Pearson proposed. We show that Pearson’s propo...
متن کاملPearson’s Test in a Large Scale Multiple Meta-Analysis
The AGEMAP project generated an 8932 by 16 matrix of p-values for whether gene i is age related in tissue j of the mouse. For each gene, a meta-analysis is required to pool over tissues, and then a multiple hypothesis testing method is required to control false discoveries. This paper looks at the meta-analysis issues raised in greater depth. The AGEMAP analysis used a test statistic first used...

— This paper begins by comparing Henri Caussinus’ concept of quasi-symmetry with a related but different concept that I shall call Karl Pearson’s quasi-symmetry; and we shall find that Caussinus’ concept is preferable to and more useful than Pearson’s concept. I shall then introduce a set of quasi-symmetric log-bilinear models that are more (∗) Reçu le 18 septembre 2001, accepté le 18 septembre...

Spearman’s rank correlation coefficient (denoted here by rs) is a nonparametric (distribution-free) rank statistic proposed by Charles Spearman as a measure of the strength of the associations between two variables. It is a measure of a monotone association that is used when the distribution of the data makes Pearson’s correlation coefficient undesirable or misleading. Spearman’s coefficient is...
