correctval: Predict the Corrected Proportional Effect
Description
Given an expected proportional effect, calculate the "corrected" proportional
effect using a model fit of Litchfield and Wilcoxon's (1949) Table 1.
Usage
correctval(val, fit)
Arguments
val
A numeric vector of expected effects (as proportions).
fit
A model object to be used to predict the "corrected" effects
(as proportions) from distexpprop5, the distance between the
expected effects (as proportions) and 0.5. Typically the output from
gamtable1().
Value
A numeric vector of corrected effects (as proportions),
the same length as val.
