Multilevel Logistic Regression Analysis Applied to Binary Contraceptive Prevalence Data
In public health, demography and sociology, large-scale surveys often follow a hierarchical data structure as the surveys are based on multistage stratified cluster sampling. The appropriate approach to analyzing such survey data is therefore based on nested sources of variability which come from different levels of the hierarchy. When the variance of the residual errors is correlated between i...
متن کاملBinary logistic regression with stratified survey data
Standard inference techniques are only valid if the design is ignorable. Two approaches that take the design into account are compared using binary logistic regression. The modelbased approach includes relevant design variables as independents and the designbased approach use design weights. The approaches are exemplified using a cross-sectional stratified mail survey, where associations betwee...
متن کاملMissing Binary Covariate Data and Imputation in Regression Models
This paper presents a simple way to handle missing values in categorical covariates, namely conditional probability imputation . Properties of this technique are given for various patterns of missing data in regression studies . An example shows its use in the proportional hazards model . The probability imputation technique is furthermore compared with multiple imputation and model-based appro...
متن کاملMaximum likelihood analysis of logistic regression models with incomplete covariate data and auxiliary information.
This article presents a new method for maximum likelihood estimation of logistic regression models with incomplete covariate data where auxiliary information is available. This auxiliary information is extraneous to the regression model of interest but predictive of the covariate with missing data. Ibrahim (1990, Journal of the American Statistical Association 85, 765-769) provides a general me...
