Hello Dear DHS experts and specialists, I was doing a multilevel regression analysis
using EDHS data in R on overweight and obesity. While I was analyzing for the year 2000,
I got the error:

"Error in pwrssUpdate(pp, resp, tol = tolPwrss, GQmat = GQmat, compDev = compDev,
: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in pwrssUpdate" ,

but for the other years I got no error. And when I tried to remove the weighting variable
it works but gives different result and I understand that weighting should not be omitted
in such analysis. I searched for any solutions to same error in stack flow but couldn't
get one. Also is it possible to use region (v025) same time as a predictor and grouping
variable. Please I am looking forward for your kindly support.

I send you the R-syntax and my dataset please help me solve this error.
Thank you so much. Stay Blessed! Stay Safe!
