This study presents a SAS program for accurate and robust prediction of longitudinal outcomes. The model overcomes data-analytic challenges in multivariate longitudinal data analysis.

Area of Science:

  • Statistics
  • Biometrics
  • Data Science

Background:

  • Longitudinal data analysis presents challenges in predicting outcomes for individuals.
  • Multivariate longitudinal datasets require specialized methods for accurate prediction.

Purpose of the Study:

  • To develop a SAS program for accurate and resistant prediction of outcomes from longitudinal data.
  • To address data-analytic difficulties inherent in long-term multivariate longitudinal studies.

Main Methods:

  • Utilizes a program written in the Statistical Analysis System (SAS).
  • Based on the Roche-Wainer-Thissen stature prediction model.
  • Employs techniques for robust prediction and cross-validation.

Main Results:
