  1. aPratt Index, in % contribution to the variance explained by the model (R2). Might not add up to 100% due to rounding errors from parameter estimates
  2. bfor dichotomous variables, the information shown is for the underlined category (reference category not underlined)
  3. call 95% confidence intervals (95%CI) – for beta-weights, correlations, r-squared, and Pratt Index – are bootstrap confidence intervals based on 1000 samples
  4. dbold numbers indicate covariates accounting for > 10% of the explained variance
  5. efull time: > 35 h/week; part time/hourly: < 35 h/week
