Simple Optimal Weighting of Cases and Controls in Case-Control Studies

Rose, Sherri; Laan, Mark van der - In: International Journal of Biostatistics 4 (2008) 1, pp. 1115-1115

Researchers of uncommon diseases are often interested in assessing potential risk factors. Given the low incidence of disease, these studies are frequently case-control in design. Such a design allows a sufficient number of cases to be obtained without extensive sampling and can increase...

Comparison of the Inverse Probability of Treatment Weighted (IPTW) Estimator With a Naïve Estimator in the Analysis of Longitudinal Data With Time-Dependent Confounding: A Simulati...

Haight, Thaddeus; Neugebauer, Romain; Tager, Ira; Laan, … - Berkeley Electronic Press - 2004

A simulation study was conducted to compare estimates from a naïve estimator, using standard conditional regression, and an IPTW (Inverse Probability of Treatment Weighted) estimator, to true causal parameters for a given MSM (Marginal Structural Model). The study was extracted from a larger...
