LW1949 1.1.0
- Constrained corrected values for observed effects of 0% to a maximum
of 10.5% and those for observed effects of 100% to a minimum of 89.5% in
keeping with the intended application of Litchfield and Wilcoxon’s
(1949) Table 1.
- Incorporated rounding in keeping with the true approach taken by
Litchfield and Wilcoxon (1949)
fitlinear() - default setting for argument
constr set to c(0.0005, 0.9995).assessfit() - exclude records with expected effects
< 0.005% or > 99.995%.correctval() - apply corrected values to expected
effects < 0.5% or > 99.5%.LWestimate() - calculate Nprime as number
of observations between ED15.5% and ED84.5%.
- Introduced greater flexibility in plotting functions.
plotDELP() - added argument grid.LWnomo1() - added argument ....
- Extended
predLines() and predLinesLP() to
cover entire x-range.
- Added citation (Adams et al. 2016).
