Causal Effects of Prenatal Drug Exposure on Birth Defects with Missing by Terathanasia
Andrew Ying, Ronghui Xu, Christina D. Chambers +1
A recent cohort study revealed a positive correlate between major structural birth defects in infants and a certain medication taken by pregnant women. To draw valid causal inferen…
Semiparametric Sieve Maximum Likelihood Estimation Under Cure Model with Partly Interval Censored and Left Truncated Data for Application to Spontaneous Abortion Data
Yuan Wu, Christina D. Chambers, Ronghui Xu
This work was motivated by observational studies in pregnancy with spontaneous abortion (SAB) as outcome. Clearly some women experience the SAB event but the rest do not. In additi…
The Impact of Confounder Selection in Propensity Scores for Rare Events Data - with Applications to Birth Defects
Ronghui Xu, Jue Hou, Christina D. Chambers
Our work was motivated by a recent study on birth defects of infants born to pregnant women exposed to a certain medication for treating chronic diseases. Outcomes such as birth de…
A Nonparametric Maximum Likelihood Approach for Partially Observed Cured Data with Left Truncation and Right-Censoring
Jue Hou, Christina D. Chambers, Ronghui Xu
Partially observed cured data occur in the analysis of spontaneous abortion (SAB) in observational studies in pregnancy. In contrast to the traditional cured data, such data has an…
