This is LaShonda, you worked with me last year on my data analysis for my research in counselor education on “The Impact of Structured Group Counseling on Resiliency, Self-Efficacy, and Racial Identity among African American Female Teenagers.”
I was browsing your website and wanted to ask, which scholars or articles would you recommend me read to become more familiar with the normal or most simplest method of imputing missing data? By the way, I orally defended my disseration three weeks ago and PASSED! Thanks for your assistance!

Hope all is well.

I m a master student. Honestly, I have very little knowledge about statistic. There is one big ? in my head now, regarding the zero values.

I am collecting secondary data whereby 2 of the variables have > 15% of zero values. These are absolute zero values, i.e. the company has no loan with bank or no fixed assets. So, it should not be consider as “missing value”. But, how should I deal with these zero values?

I am now in the process of cleaning my data. Later on will analyze it using logistic regression. Really hope that you can give me some guidance so that I can move on. Thanks a lot!

I’m confused about 1 thing. My data are MCAR, so I see that I can use any of the methods. But in SPSS (I’m using 19.0), it appears that the Missing Value Analysis (which allows for specification of listwise, pairwise, EM, etc.) is separate from Multiple Imputation, which uses MCMC. Does that mean that listwise, pairwise, etc. are single imputation methods?

If so, then I should just use Multiple Imputation, right? The SPSS manual implies that this is more accurate. But I can’t tell if/why I am supposed to do BOTH the listwise/pairwise/EM and the multiple imputation methods.

Any advice?

Thanks,
Robby

I am a graduate student at the University of Utah. I came across your website and found it helpful. Thus I have a question. I have 88 surveys using likert or likert-type scales. Most of the items create scales.

I have some missing data, but it is MCAR. I wanted to use the mean of the same person’s other responses. But, I am struggling on how to enter to calculate this in SPSS. Any suggestions.

Thanks!
