This study uses linear regression to analyze factors influencing twinning rates, identifying maternal age, parity, and marital status as key predictors. The research also explores the secular decline in twinning using model-building techniques.

Area of Science:

  • Demography
  • Biostatistics

Background:

  • Twinning rates exhibit significant variations globally.
  • Understanding the determinants of twinning is crucial for demographic and health research.

Purpose of the Study:

  • To explain variations in twinning rates using statistical models.
  • To investigate the secular decline in twinning rates.
  • To identify key demographic factors influencing twinning.

Main Methods:

  • Application of linear regression models.
  • Analysis of international datasets.
  • Utilizing model-building techniques for trend analysis.

Main Results:

  • Maternal age, parity, and marital status identified as primary regressors influencing twinning rates.

  • Linear regression effectively compares the impact of various factors on twinning.
  • Model building aids in understanding the secular decline in twinning.

    • Conclusions:

    • Linear regression provides a robust framework for analyzing twinning rate determinants.
    • Sufficiently disaggregated data is essential for accurate regression analysis.
    • Demographic factors play a significant role in shaping twinning trends.
