We consider two-level models where a continuous response R and continuous covariates C are assumed missing at random. Inferences based on maximum likelihood or Bayes are routinely made by estimating their joint normal distribution from observed data R[subscript obs] and C[subscript obs]. However, if the model for R given C includes random…

Viewed through a social justice lens, preschool expulsion is an educational equity issue. This study focused on prior expulsion from preschool and child-care in a longitudinal study of 203 autistic children, ages 4 to 7. By parent report, 16%--one out of six autistic children--had been expelled from a preschool or child-care setting prior to…

Establishing causal links when experiments are not feasible is an important challenge for psychology researchers. The question of whether parents' spanking causes children's externalizing behavior problems poses such a challenge because randomized experiments of spanking are unethical, and correlational studies cannot rule out potential selection…

This study examined the relationship between school mobility for Colorado students in foster care and educational attainment outcomes, specifically earning high school diploma, a high school equivalency diploma (e.g., through examination such as a GED), or exiting the K-12 system without a credential. Multinomial logistic regression was utilized…

We use a unique longitudinal sample of student teachers ("interns") from six Washington state teacher training institutions to investigate patterns of entry into the teaching workforce. We estimate split population models that simultaneously estimate the impact of individual characteristics and student teaching experiences on the timing…
