DEA error

[Victoria Romanova]

Hi! I am trying to do a DEA analysis in Stata, but I have an error:

rankdea(): 3301 subscript invalid
<istmt>: - function returned error
r(3301);

How can I solve it? I have not faced it before... Thanks!

Me too. It's still running with example data, but my data.

Hi, I am completely new to STATA as well as DEA which is for my dissertation project. i am frequently encountered with this problem "matrix has missing values r(504);" Though i don't find any missing values in my data. For similar data set I have successfully conducted the score but this particular dataset I am stuck into. Is there anyone who can help me on this? I am using STATA18. Thanks
