How to Use SPSS: Little's Missing Completely at Random (MCAR) Test

Test to determine if missing data is missing in a random or non-random pattern. Assists in deciding which technique may be most appropriate for replacing missing data.

Thanks for this demonstration. I performed this technique on my data but SPSS is not calculating the Little's test. This is what I get: "Little's MCAR test: Chi-Square = .000, DF = 0, Sig. = ." What could be the problem?

+Ka Pa, check to be sure your variables are categorized properly in the Variable View tab. The data Type should be labeled as Numeric.

Hello. I noticed that the output did not include any results for the categorical variable  "sex". Does this mean that the Little´s MCAR test doesn´t work for such type of variables? Thanks!

Thank you for posting. When I run this, I got a little note that says "the em algorithm failed to converge in 25 iterations." Any insight as to what this means?

What can you eventually say about the randomness of the missing values on the categorical variable?

From the chi square test we have DF= 9, chi square = 6.225, sig= 0.717.
From the chi square table we have for DF= 9, 5.38<6.225<6.39 and 0.7<p<0.8. The interpretation is: With the probability 70% there is no significant deviation from the expected value. H0 is accepted. The deviation is not significant. End of the story. All the videos I have seen are not so clear when it comes to interpretation.

Thank you. What are the other tables in the output .. are they not required for this analysis?

Does Little's MCAR test only work for quantitative variables? When I select only categorical variables, Little's MCAR results are not included in the output.

Hey....I am currently Working on a Survey data.. i have few queries....
1) How to find the data is random or Non-random data?  

I have done Little MCAR test - Chi Square - 592350, DF - 590454,  Sig =0.37

Is the data is random data or not ???

What about when Little's MCAR shows that the data is not missing completely at random, does the test give any info as to point out where the problem might be? Where to go after that?
