  1. NB: Data refer to upper secondary teachers. Logit model for: Declaring cost as a barrier to professional development as a binary outcome variable. NB: B (beta regression coefficient for the logit); b.se (standard error for B). NB: Model performance: LL (− 2 Log likelihood coefficient) = 337,729.98 (s.e. 10,987.38); CSR (Cox and Snell R2 coefficient) = 0.01 (s.e. 0.00); NKR (Nagelkerke R2 coefficient) = 0.01 (s.e. 0.00)
