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
)

Arguments

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)

Value

list with the worth values for each item and the total number of simulated combinations based on simOption
