Test Score: test score probability of being top half: probability of test score being in the top half. See footnote 10 of the paper probability of being to 30%: probability of test score being in the 30%. See footnote 10 of the paper \tilde{D}: if top half and chose skill in 50-50 bet: "50-50 bet, chose skill" times "probability of being top half" \tilde{D}: if top half and chose skill in 60-50 bet: "60-50 bet, chose skill" times "probability of being top half" \tilde{D}: if top half and chose skill in 50-70 bet: "50-70 bet, chose skill" times "probability of being top 30%" Experiment_I_BDM.csv csv version of Experiment_I_BDM.xlsx Exp_II.R R code to generate the results in Table 5 expm2.xlsx Data file used in Exp_II.R Original data available at http://learnmoore.org/mooredata/OJD/ Each column is titled with a number. The column titled "a" stores a binary variable which is one if the score exceeds a. expm2.csv csv version of expm2.xlsx expm2actual.xlsx Data file used in Exp_II.R Original data available at http://learnmoore.org/mooredata/OJD/ Each column is titled with a number. The column titled "a" stores a variable which is constructed by multiplying "a" in expm2.xlsx and the probability of being in the top half. See footnote 12 in the paper. expm2actual.csv csv version of expm2actual.xlsx ***** The three .xlsx files are stored in jo-xlsx-files.zip. All other files are ASCII files in DOS format and are stored in jo-text-files.zip. For the latter, Unix/Linux users should use "unzip -a".
