retrodesign: Tools for Type S (Sign) and Type M (Magnitude) Errors
Provides tools for working with Type S (Sign) and
Type M (Magnitude) errors, as proposed in Gelman and Tuerlinckx (2000)
<doi:10.1007/s001800000040> and
Gelman & Carlin (2014) <doi:10.1177/1745691614551642>.
In addition to simply calculating the probability of
Type S/M error, the package includes functions for calculating these errors
across a variety of effect sizes for comparison, and recommended sample size
given "tolerances" for Type S/M errors. To improve the speed of these
calculations, closed forms solutions for the probability of a Type S/M error
from Lu, Qiu, and Deng (2018) <doi:10.1111/bmsp.12132>
are implemented. As of 1.0.0, this includes
support only for simple research designs. See the
package vignette for a fuller exposition on how Type S/M errors arise in
research, and how to analyze them using the type of design analysis proposed
in the above papers.
