can I use GWR with zero-inflated data?

Alper:

Without knowing exactly what type of data that might be, I would say the 
data probably are not the best set for GWR analysis (not even for OLS, I 
might add) due to the lack of variation of your dependent variable. In 
addition, nominal (coded, I assume?) independent variable can cause no 
variation at all in locally weighted calibration.

Is there a compelling reason that you believe GWR is a reasonable choice 
for your data analysis?

Hope this helps.

Cheers,
Danlin

Alper ALTINOK ??:

 

Dear all,
 
I want to hear your opinions on applicability of GWR method on the following kind of data;
 
Dependent:
-Numeric > continuous. With excess zeroes (about %70).
 
Independent(s):
-Numeric > nominal
-Character > nominal
-Numeric > ordinal
