Latent Transition Analysis: Benefits of a Latent Variable Approach to Modeling Transitions in Substance Use [PDF]

Journal of Drug Issues, 2010
We apply latent transition analysis (LTA) to characterize transitions over time in substance use behavior profiles among first-year college students. Advantages of modeling substance use behavior as a categorical latent variable are demonstrated. Alcohol use (any drinking and binge drinking), cigarette use, and marijuana use were assessed in a sample ...

Learning scientific reasoning: A latent transition analysis

Learning and Individual Differences, 2021
Primary education in many countries enables children to learn the scientific reasoning skills of hypothesizing, experimenting, interpreting data and drawing conclusions. Research has shown that these component skills develop at a different pace and with substantial variation among same-age children.
