lcsm

lcsm generates model syntax and path-diagram visualizations for univariate and bivariate latent change score models (LCSMs) to estimate temporal trajectories and associations between constructs in longitudinal behavioral-science data.

Key Features:

• Univariate and Bivariate LCSMs: Supports specification and analysis of both univariate and bivariate latent change score models for longitudinal data.
• Model Syntax Generation: Generates syntax for basic univariate and bivariate LCSMs with various specifications.
• Path Diagram Visualization: Produces simplified path diagrams to visualize model specifications and structural relationships.

Scientific Applications:

• Developmental Trajectories: Estimate trajectories of single constructs over time in longitudinal studies.
• Change Associations: Explore associations between changes in two constructs across temporal dimensions using bivariate LCSMs.
• Intervention and Causal Inquiry: Assess intervention impacts over time and investigate causal relationships between evolving psychological or social phenomena.

Methodology:

Generates model syntax for latent change score models across multiple specifications and visualizes models as simplified path diagrams.
