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.

Re: [amelia] Amelia Digest, Vol 124, Issue 1

by Andrew Grannell

Hi Lisandra, I encountered the same problem recently when I was trying to install and run AmeliaView. I found that loading the Amelia package in R (version 3.0.3) first fixed the issue. To do this, I opened R and selected the Packages menu and clicked on "Load package...". Then a window popped up with all the packages I have installed in R. I selected "Amelia" from the list and clicked Ok. Once I did this, I tried to open AmeliaView again and it worked fine for me. I hope this helps you!!

Help with AmeliaView GUI Installation

by lisa perez

Greetings! I have tried several times to install AmeliaView (GUI versions 1.5 and 1.7) but without any success. A black window (command shell) was pop up and disappeared in milliseconds. I tested with R version 3.0.3 and 3.0.2. Furthermore, installation was attempted using different Os systems (Windows 7/ 32-bit and Windows XP). I will really appreciate any help you can provide.
