Theoretical sampling designs for a UK birth cohort with potential accelerated design

Theoretical sampling designs for a UK birth cohort with potential accelerated design
Theoretical sampling designs for a UK birth cohort with potential accelerated design
Executive Summary

Accelerated Longitudinal Designs (ALDs) have several advantages over single cohort designs, specifically the ability to estimate and adjust for cohort effect differences and produce results in a shorter period. These are traded off against additional model complexity in analysis and challenges in recruitment of additional sample cases in the field.

There are several properties of ALDs which can be varied; analyses based on the power to detect cohort differences in a linear model for age effects show that small numbers of cohorts have the best chance to improve the properties of the design and speed up data availability across the age range of interest while remaining practical to implement.

Further work is needed on methods to determine sample sizes to meet variance constraints for a range of analytical parameters, and to determine how best to produce a general purpose design which can meet a wide range of user needs.

Abstract

Executive Summary

Accelerated Longitudinal Designs (ALDs) have several advantages over single cohort designs, specifically the ability to estimate and adjust for cohort effect differences and produce results in a shorter period. These are traded off against additional model complexity in analysis and challenges in recruitment of additional sample cases in the field.

There are several properties of ALDs which can be varied; analyses based on the power to detect cohort differences in a linear model for age effects show that small numbers of cohorts have the best chance to improve the properties of the design and speed up data availability across the age range of interest while remaining practical to implement.

Further work is needed on methods to determine sample sizes to meet variance constraints for a range of analytical parameters, and to determine how best to produce a general purpose design which can meet a wide range of user needs.
