Statistical power analyses using G*Power 3.1: Tests for correlation and regression analyses
G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchn...
Some Tests of Specification for Panel Data: Monte Carlo Evidence and an Application to Employment Equations
This paper presents specification tests that are applicable after estimating a dynamic model from panel data by the generalized method of moments (GMM), and studies the practica...
Development and validation of brief measures of positive and negative affect: The PANAS scales.
In recent studies of the structure of affect, positive and negative affect have consistently emerged as two dominant and relatively independent dimensions. A number of mood scal...
Gaussian basis sets for use in correlated molecular calculations. I. The atoms boron through neon and hydrogen
In the past, basis sets for use in correlated molecular calculations have largely been taken from single configuration calculations. Recently, Almlöf, Taylor, and co-workers hav...
