Regression Results.

The table displays the regression results for our subsample of players who played 1,000 hands or more over the first six months of our sample period (Period 1) and at least 1 hand over the second six months (Period 2). The dependent variable is either the standard performance measure (Panel A) or the performance robustness measure (Panel B). The standard performance measure is defined as the average number of big blinds won per hundred hands after correction for rake (bb/100). The performance robustness measure is the average number of big blinds won after correction for rake divided by its estimated standard error. All explanatory variables are calculated using data from Period 1 only. SPM is the player’s standard performance measure. PRM is her performance robustness measure. Hands (log) is the natural logarithm of the number of hands played. Tightness is one minus the proportion of hands in which the player voluntarily wagered money in the first betting round. Aggressiveness is the number of times the player led the betting as a proportion of the total number of times she voluntarily wagered money. Tournaments is the player’s tournament ability rating from the SharkScope database immediately before the start of Period 2. The results reported in Panel A are weighted least squares regression results with the ratio of a player’s number of hands and her sample variance of the number of big blinds won in Period 2 as weight. Panel B presents ordinary least squares results. The p-values are in parentheses.
