A dataset containing 168,386 total rounds of play in 30 different variations on the iterated prisoner's dilemma games. The data comes from J.J. Nay and Y. Vorobeychik, "Predicting Human Cooperation," PLOS ONE 11(5), e0155656 (2016).

NV_games

A data frame with 168,386 rows and 51 variables:

period: Which turn of the given game
my.decision: The player's move in this turn
risk: Boolean variable: 1 indicates stochastic payoffs, 0 deterministic payoffs
delta: Probability the game ends after each round
r1: Normalized difference in payoff between both players cooperating and both defecting
r2: Normalized difference in payoff between both players cooperating and the payoff for being a sucker (cooperating when the opponent defects)
error: Probability that the player's intended move is switched to the opposite move
data: Which dataset did this game come from: AM = Andreoni & Miller; BR = Bereby-Meyer & Roth; DB = Dal Bo; DF = Dal Bo & Frechette; DO = Duffy & Ochs; FO = Friedman & Oprea; FR = Fudenberg, Rand, & Dreber; and KS = Kunreuther, Silvasi, Bradlow & Small

r: Reward: payoff when both players cooperate

infin: Boolean: 1 indicates infinite game with probability delta of ending at each round; 0 indicates pre-determined number of rounds
contin: Boolean: 1 indicates the game is played in continuous time; 0 indicates discrete rounds
group: Which group (version of the game) is being played?
