Computing spatial weights for Moran's I #spmap #shp2dta #spatwmat

[Harish Kumar]

Dear Statalist,

I am doing district level analysis (640 districts) on various health related indicators using DHS India. I am using the shp2dta to covert my shape file in dta file. I have pasted the sample output below and want to understand the numbers (x_cen and y_cen). Are these area variables or showing some distance in kilometers or miles? I am using the spatwmat command to compute spatial weights and there is need to give correct band values which can be given after understanding the x_cen and y_cen values. The effort is to calculate Moran's I and related analysis in Stata. Your help will be much appreciated.



shp2dta using "E:\Dropbox\Shepefile_India\India_District_2011_up dated", ///
data("dis_data") coor("cor") genc(cen) genid(id) replace


id x_cen y_cen
1 3268826 176869.2
2 3147581 1035534

**(id is 640 districts)


spatwmat, name(Wt) xcoord(x_cen) ycoord(y_cen) standardize eigenval(E) band(0 800000)



With Thanks

Hi Harish,

I'm also trying to exploit district-level panel data of India.
But as I enter below commands, Stata17 keeps running for a while and after that goes- Stata Not Responding!

global band 10
global xcoord arcgis_lon
global ycoord arcgis_lat
spatwmat, name(W) xcoord($xcoord) ycoord($ycoord) band(0 $band) standardize eigenval(E)

Do you've any suggestions?

Thanks,
Sourya
