Open Stata and enter "help ginidesc". You will then see how to download this command and to access the help that goes with it. Report message to a moderatorRe: Missing data [message #12536 is a reply to message #8721] Fri, 09 June 2017 09:04 filotempo Messages: 2Registered: Octob...
In this presentation, we will first highlight the issues of missing data in longitudinal records and provide examples of the limitations of standard methods of multiple imputation. We will then demonstrate the new twofold user-written Stata command that implements the twofold fully conditional ...
Sometimes, a mean probing depth value might be recorded, later judged to be wrong, and deleted from the dataset, which also gives rise to missing data. Missing data can occur in the outcomes, one or more covariates, or both the outcomes and covariates. A participant's probing depth could...

How is Missing Data Identified? Researchers working with statistical programs like SAS, SPSS, Stata rely on manual statistical procedures to identify, delete, and replace missing values. But there’s a problem. Most of these programs automatically remove missing values from any analysis you run. As...
Dear Statalist, I need to impute the missing data in a dataset by matching it to the already existing data. I have never worked with either imputation or matching and am at a loss. I would deeply appreciate any advice. My dataset contains background data for individuals who participated in...
EM Imputation is available in SAS, Stata, R, and SPSS Missing Values Analysis module. Approaches to Missing Data: the Good, the Bad, and the Unthinkable Learn the different methods for dealing with missing data and how they work in different missing data situations. Take Me to The Video!
I therefore tried to take a different approach by imputing the missing data in the covariates. I tried this with both stata and mplus. I am really new to imputations. In mplus when I try to use the imputed data I get:"ERROR The number of observations is 0. Check your data and ...
We also assessed, where relevant, how missing data were treated in the context of these features. In addition, the software used for the analysis was also extracted by searching for ‘Stata’, ‘SAS’, ‘SPSS’, ‘R’ and ‘plus’ (for S-plus and Mplus). Papers which did not mention...
