R help - Dec 2015 - LW1949 – new package for evaluating dose-effect experiments

LW1949 1.0.0 is now available on CRAN.



LW1949 automates the steps taken in Litchfield and Wilcoxon?s (1949) manual
approach to evaluating dose-effect experiments. Letting the computer do the
work saves time and yields the best fit possible using the Litchfield
Wilcoxon approach (by minimizing the chi-squared statistic).



A brief demonstration of LW1949 is given in this web app,

An example of how to use the functions in LW1949 is given in this vignette,
