Multiple imputation for an incomplete covariate that is a ratio
We are concerned with multiple imputation of the ratio of two variables, which is to be used as a covariate in a regression analysis. If the numerator and denominator are not missing simultaneously, it seems sensible to make use of the observed variable in the imputation model. One such strategy is to impute missing values for the numerator and denominator, or the log-transformed numerator and ...

1. Missing data problems are ubiquitous in many fields, including official statistics, where one of the common treatments of missing data is ratio imputation (de Waal et al., 2011; Thompson & Washington, 2012; Office for National Statistics, 2014). On the other hand, multiple imputation has been the recommended practice from statisticians (Rubin, 1987; Little & Rubin, 2002). Among statisticians...
متن کاملA multiple - imputation Metropolis version of the EM algorithm
The algorithm (Dempster et al., 1977) is a general iterative method for finding the maximum likelihood estimate of the parameters of models with incomplete data. Roughly speaking, the algorithm shares out the task of maximising a complicated likelihood function by performing a series of maximisations, in the -steps, of simpler functions calculated in the -steps. Clearly the algorithm is...
متن کاملGillespieSSA: Implementing the Stochastic Simulation Algorithm in R
The deterministic dynamics of populations in continuous time are traditionally described using coupled, first-order ordinary differential equations. While this approach is accurate for large systems, it is often inadequate for small systems where key species may be present in small numbers or where key reactions occur at a low rate. The Gillespie stochastic simulation algorithm (SSA) is a proce...
متن کاملConvergence Properties of a Sequential Regression Multiple Imputation Algorithm
A sequential regression or chained equations imputation approach is a Gibbs sampling type iterative algorithm that imputes the missing values using a sequence of conditional regression models. It is a flexible approach for handling different types of variables and complex data structures. Many simulation studies have shown that the multiple imputation inferences based on this procedure have des...
