bias


Prediction errors of 48-hour ahead MM5 forecasts of surface
temperature measured at 96 different locations in the US Pacific
Northwest on January 3, 2000. The prediction error, or "bias", is
the difference between the forecasted and observed surface
temperature. (MM5 is the fifth-generation Pennsylvania State
University -- National Center for Atmospheric Research Mesoscale
Model.)


datasets

Statistical tests widely utilized in biostatistics, public policy, and law. Along with the well-known tests for equality of means and variances, randomness,
measures of relative variability etc, the package contains new robust tests of symmetry,
omnibus and directional tests of normality, and their graphical counterparts such as
Robust QQ plot; a robust trend tests for variances etc. All implemented tests and methods
are illustrated by simulations and real-life examples from legal statistics, economics,
and biostatistics.
