Score 5.5 trial probability discounting from Qualtrics template

Usage

score_pd(df)

Arguments

df: A dataframe containing all the columns

Value

A dataframe with id, indexes, response, h value, and effective probability 50.

Details

Currently assumes the attending questions are present and labeled "Attend-LL" and "Attend-SS"

Responses may be exported from Qualtrics either as choice text (the certain option contains "for sure", the uncertain option "chance") or as the template's numeric codes. Numeric codes are read per item: every I item and Attend-SS code 1 = the certain option and 2 = the uncertain option, while Attend-LL lists the uncertain option first (1 = "with a 1% chance", 2 = "for sure"). Blank cells are treated as unanswered and dropped; any other unrecognised value is an error.
