Nearstat Error Message

[Bianca Duelken]

Dear Statalist-Community,

I am trying to calculate the distance between two datsets using their latitude & longitude locations and the 'nearstat' command.

Following, the used commands are listed:

************************************************** ****************************
use "$data\Prep_Buffer_DHS.dta", clear

append using "$data\All_Location_Insa_nodup.dta", keep(id latitude longitude)

* Sort so that nearstat will run, putting all projects first

gsort -id

* First count how many projects are within 200 km to know how many loops->to run nearstat

foreach dist in 15 25 50 75 100 200 {
nearstat LATNUM LONGNUM, ///
near(latitude longitude) distvar(_1LSLAdist`dist') ///
ncount(numberwithin`dist') dband(0 `dist') favor(speed)
}

drop _1LSLAdist15 _1LSLAdist25 _1LSLAdist50 _1LSLAdist75 _1LSLAdist100 _1LSLAdist200

************************************************** **********************************

When I run the 'nearstat' command, I get the following error message:

'The order for the nearest neighbor cannot be greater than the number of near features.'

Does anyone know how to interpret the error message? I could'nt find a solution yet.

Thank you very much for your support in advance and warm greetings !
