The bimworth
calculates the worth model using the curated preference
test data (e.g, from bimpre).
bimworth( ydata = NULL, GT = NULL, simOpt = NULL, randOP = FALSE, intrans = FALSE, showPlot = FALSE, ylim = c(0, 0.8), size = 5, verbose = FALSE )
ydata | curated data.frame obtained from the bimpre function |
---|---|
GT | item list with the ground truth (GT; letters are case sensitive!) |
simOpt | item to be checked (this can be an item from the GT or a new one. Remove the item from GT if specified here!) |
randOP | randomize the test result for open/undecided pairs (e.g., data marked as ties) |
intrans | calculate intransitivity during worth value estimation (calculation intense! TRUE/FALSE) |
showPlot | plot the worth plot (c("FALSE","worth","coef")) |
ylim | y limits of the worth plot (default c(0,0.7)) |
size | point size in the worth plot (default = 7) |
verbose | show model outputs (default= FALSE) |
list with the worth values for each item and the total number of simulated combinations based on simOption
