Help DEA command errors and Network DEA

[Bernardo Pinho]

Hi,

I am using DEA command wchich provided me the following errors under CRS with an input-orientation:

No Solution(LOOP greater than maxiter):[DMUi=17][LOOP=16001]CRS-IN-SI-PI
No Solution(Remaining artificails are not zero):[DMUi=24][LOOP=20]CRS-IN-SI-PI
No Solution(LOOP greater than maxiter):[DMUi=30][LOOP=16001]CRS-IN-SI-PI
No Solution(No more candidate for entering variable):[DMUi=7][LOOP=6]CRS-IN-SII-PI
No Solution(No more candidate for entering variable):[DMUi=46][LOOP=14]CRS-IN-SII-PI
No Solution(No more candidate for entering variable):[DMUi=49][LOOP=32]CRS-IN-SII-PI
No Solution(Remaining artificails are not zero):[DMUi=50][LOOP=10]CRS-IN-SII-PI
No Solution(No more candidate for entering variable):[DMUi=51][LOOP=26]CRS-IN-SII-PI

Also, under VRS with an output-orientation the 1st ranked DMU presents an efficiency score lower than 1 (0.5) but the others have efficiency scores higher than 1. What does this mean?

Could you please also provide me a general guidance about how to implement Network DEA in STATA in case there exists any differences to standard DEA ?

Thanks!!

Hi Bernardo,

Thank youu!!

Hi, I am also using malmq2 in STATA17 to analyze changes in efficiency over time. I've set up the xtset for the panel id and time variable. But can't seem to successfully run the malmq2 command. I keep getting below error.
r(3021)
sdf_o(): 3021 class compiled at different times
<istmt>: - function returned error</istmt>

Za Jimenez, that is exactly what is happening to me! Did you figure it out?
