  1. aBased on the assumption of normally distributed regression coefficients, the 95 % predictive interval indicates the range of values between which 95 % of the regression coefficients are estimated to lie (Hox, 2010). The intervals were calculated based on a model without Level 2 predictors
  2. bBased on the assumption of normally distributed regression coefficients, this value indicates the percentages of regression coefficients that are positive (Hox, 2010). The percentages were calculated based on a model without Level 2 predictors
