conclusions the current study provided evidence for the utility of the belief-based model in the prediction of oral health behaviors. it could be suggested that oral health behavior can be promoted by reducing the perceived barriers and enhancing the students’ knowledge of oral and dental hygiene. background oral and dental health diseases can affect the general health of students. objectives t...

This article considers Monte Carlo integration under rejection sampling or Metropolis-Hastings sampling. Each algorithm involves accepting or rejecting observations from proposal distributions other than a target distribution. While taking a likelihood approach, we basically treat the sampling scheme as a random design, and define a stratified estimator of the baseline measure. We establish tha...
