Power Analysis for Stepped Wedge Trials with Two Treatments
Phillip T. Sundin, Catherine M. Crespi
Stepped wedge designs (SWDs) are designs for cluster randomized trials that feature staggered, unidirectional cross-over, typically from a control to a treatment condition. Existin…
Causal inference for multiple continuous exposures via the multivariate generalized propensity score
Justin R. Williams, Catherine M. Crespi
The generalized propensity score (GPS) is an extension of the propensity score for use with quantitative or continuous exposures (e.g., dose of medication or years of education). C…
Modeling Variables with a Detection Limit using a Truncated Normal Distribution with Censoring
Justin R. Williams, Hyung-Woo Kim, Catherine M. Crespi
When data are collected subject to a detection limit, observations below the detection limit may be considered censored. In addition, the domain of such observations may be restric…
Addressing missing data mechanism uncertainty using multiple-model multiple imputation: Application to a longitudinal clinical trial
Juned Siddique, Ofer Harel, Catherine M. Crespi
We present a framework for generating multiple imputations for continuous data when the missing data mechanism is unknown. Imputations are generated from more than one imputation m…
