Simple imputation methods were inadequate for missing not at random (MNAR) quality of life data
OBJECTIVE QoL data were routinely collected in a randomised controlled trial (RCT), which employed a reminder system, retrieving about 50% of data originally missing. The objective was to use this unique feature to evaluate possible missingness mechanisms and to assess the accuracy of simple imputation methods. METHODS Those patients responding after reminder were regarded as providing missin...
متن کاملimputation in missing not at random snps data using em algorithm
the relation between single nucleotide polymorphisms (snps) and some diseases has been concerned by many researchers. also the missing snps are quite common in genetic association studies. hence, this article investigates the relation between existing snps in dnmt1 of human chromosome 19 with colorectal cancer. this article aims is to presents an imputation method for missing snps not at random...
متن کاملA Technique for Incorporating Data Missing Not at Random (MNAR) into Bayesian Networks
We present a technique for incorporating data attributes that are supposed Missing Not at Random (MNAR) into Bayesian Networks (BNs). While traditional methods of incorporating data that is Missing at Random (MAR) into BNs are well documented, there are fewer tested methods for discovering and incorporating data Missing Not at Random (MNAR). We present a review of literature in BNs and missing ...
متن کاملImputation methods for quantile estimation under missing at random
Imputation is frequently used to handle missing data for which multiple imputation is a popular technique. We propose a fractional hot deck imputation which produces a valid variance estimator for quantiles. In the proposed method, the imputed values are chosen from the set of respondents and are assigned with proper fractional weights that use a density function for the working model. In addit...
متن کاملAdditional Support for Simple Imputation of Missing Quality of Life Data in Nursing Research
Background. Missing data are a significant problem in health-related quality of life (HRQOL) research. We evaluated two imputation approaches: missing data estimation (MDE) and assignment of mean score (AMS). Methods. HRQOL data were collected using the Medical Outcomes Trust SF-12. Missing data were estimated using both approaches, summary statistics were produced for both, and results were co...
