Amelia in Stata, mi estimate: svy commands

by Evelyn Chan

Hello I have imputed data that has been saved as a Stata stacked dataset. I am trying to run mi estimate: svy commands, but I have been having trouble getting Stata to recognize the imputed variables. The data I am using is survey data so I set it first using the svyset command and then the mi set command. I then use the mi register command to identify regular and imputed variables. However I continually get a 2(2000) error, in which Stata does not recognize the imputations. Any suggestions on where I have made a mistake. Appreciate the help. Thank you, Evelyn

How to create a combined correlation matrix after using Amelia

by Estefania Ruiz

Hello, I have a dataset with some missing values, I used Amelia on this dataset and ended up with 5 imputed datasets. I calculated the correlation matrix for each dataset, therefore I have 5 correlation matrices. I would like to know how to combine these 5 matrices in order to get one final correlation matrix for my dataset? Thank you very much ERV

Imputations with Amelia II

by Yunyan Zhang

Dear Amelia Initiator, This is Yunyan Zhang. I am a senior student majoring in Industrial and Operations Engineering at the University of Michigan. Our team is doing our senior design and we want to use R to deal with our missing data. What we want is to impute the missing data with EM algorithm. We found Amelia II on Inside R website and tried Amelia II. However, we are confused with the return value of *amelia {Amelia}. *Will it return the imputed data or something else? If it does not return the imputed dataset, what is the next step for us to impute our missing data in the original dataset so that we could proceed to the next step. Thanks for your help and patience. Sincerely, Yunyan Zhang (Jackie) 张云艳 Industrial and Operations Engineering, B.S.E. 2014 College of Engineering, University of Michigan Electrical and Computer Engineering, B.S.E. 2014 UM-SJTU Joint Institute, Shanghai Jiao Tong University jackiezh(a)umich.edu | 734-757-3234

Crashing on example data when time and cross-section interact

by Calla M Hummel

Dear Amelia Team, I've been having problems with Amelia crashing frequently. I can run it with a few splines, but if I interact time and cross-section, it crashes. This is the case whether I run it on my data, the example data, in R, in AmeliaView, or on someone else's computer. Help? Also, whenever I try to include similar variables -- alternative measures, for example -- I get a collinearity warning. I'd like to be able to impute everything, including all my robustness check measures, together. The documentation makes it sound like Amelia can handle that. Thank you, Calla Hummel

Re: [amelia] Help with installation

by Ista Zahn

Hi Lisa, That procedure seems unnecessarily complicated and error-prone. You should be able to just run install.packages("Amelia") at the R prompt.

Help with installation

by CRISTINA HERRERO JAUREGUI

Hello, I have tried several times to run Amelia, either in R or Amelia View with no success. Amelia View just dissappears when double click, and in R 3.0.2 I get the following Error message "Error: package 'Amelia' was built before R 3.0.0: please re-install it". Does it mean that I have to install a previous version of R? I have downloaded the latest version of Amelia!! thanks very much in advance, Cristina
