Statistics notes: Calculating correlation coefficients with repeated observations: Part 2--correlation between subjects

Calculating correlation coefficients with repeated observations: Part 1--Correlation within subjects.

The logrank test.

Perhaps the finest series of short articles on the use of statistics is the occasional series of Statistics Notes started in 1994 by the British Medical Journal. It should be required reading in any introductory statistics course. The full text of all but the first ten articles is available is available on the World Wide Web. The articles are listed here chronologically. Absence of evidence is ...

Notes on Certain ( 0 , 2 ) Correlation Functions

In this paper we shall describe some correlation function computations in perturbative heterotic strings that, for example, in certain circumstances can lend themselves to a heterotic generalization of quantum cohomology calculations. Ordinary quantum chiral rings reflect worldsheet instanton corrections to correlation functions involving products of elements of Dolbeault cohomology groups on t...

Statistics for dental researcher, Part 2: Descriptive statistics

Descriptive statistics is the process of summarizing gathered raw data from a research and creating useful statistics, which help the better understanding of data. According to the types of variables, which consist of qualitative and quantitative variables, some descriptive statistics have been introduced. Frequency percentage is used in qualitative data, and mean, median, mode, standard deviat...
