Error in statistical tests of error in statistical tests

BACKGROUND A recent paper found that terminal digits of statistical values in Nature deviated significantly from an equiprobable distribution, indicating errors or inconsistencies in rounding. This finding, as well as the discovery that a large percentage of p values were inconsistent with reported test statistics, led to a great deal of concern in the popular press and scientific community. Th...

Basic Statistical Tests For Gross Error Detection

The technique of data reconciliation crucially depends on the assumption that only random errors are present in the data and systematic errors either in the measurements or the model equations are not present. If this assumption is invalid, reconciliation can lead to large adjustments being made to the measured values, and the resulting estimates can be very inaccurate and even infeasible. Thus...

Statistical Error in

We present predictions for the statistical error due to nite sampling in the presence of thermal uctuations in molecular simulation algorithms. The expressions are derived using equilibrium statistical mechanics. The results show that the number of samples needed to adequately resolve the owweld scales as the inverse square of the Mach number. Agreement of the theory with direct Monte Carlo sim...
