Applied Stats Workshop (Gov 3009)

Date: 

Wednesday, February 1, 2017, 12:00pm to 1:30pm

The Applied Statistics Workshop (Gov 3009) meets all academic year, Wednesdays, 12pm-1:30pm, in CGIS K354. This workshop is a forum for advanced graduate students, faculty, and visiting scholars to present and discuss methodological or empirical work in progress in an interdisciplinary setting. The workshop features a tour of Harvard's statistical innovations and applications with weekly stops in different fields and disciplines and includes occasional presentations by invited speakers.  Free lunch is provided.

Title: Maximum likelihood multiple imputation: A more efficient approach to repairing and analyzing incomplete data

 

Abstract: Maximum likelihood multiple imputation (MLMI) is a form of multiple imputation (MI) that imputes values conditionally on a maximum likelihood estimate of the parameters. MLMI contrasts with the most popular form of MI, posterior draw multiple imputation (PDMI), which imputes values conditionally on an estimate drawn at random from the posterior distribution of the parameters. Despite being less popular, MLMI is less computationally intensive and yields more efficient point estimates than PDMI. A barrier to the use of MLMI has been the difficulty of estimating standard errors and confidence intervals. We present three straightforward solutions to the standard error problem.
