Melogit and Weights [message #19634]

Hello,

I am trying to fit a multilevel model examining HIV risk behaviors among those living with HIV using a pooled data from 23 countries.

My model nests individuals (level 1) into clusters (level 2). For melogit, I am aware I need to set weights at the two levels of my analysis, yet DHS only provides one weight.

From my review of forum here ( https://userforum.dhsprogram.com/index.php?t=msg&goto=13 522&&srch=multilevel+weights#msg_13522), I understand I can svyset my data, using the following:

gen weight=hiv05/1000000
gen weight2=1
svyset idhspsu, weight(weight) strata(idhsstrata) singleunit(centered) || _n, weight(weight2)

When I run my basic melogit, <svy: melogit condomless_spouse sex || idhspsu: >

I get the following error: "weights in variable weight not constant within groups defined by: idhspsu an error occurred when svy executed melogit"

I am sure I may not be doing something wrong here. I would be very grateful if any of you could point me in te right direction.

Thanks in advance of your assistance.
