라고 경고문이 뜨는데 , gwr을 하기 위해서는 어떻게 해야하나요?
%=============GWR ANALYSIS========%
%=============exponential weight========%
info.dtype='exponential';
res1=gwr(ln_sale,x,xc,yc,info);
prt(res1, vnames);
more on;

Hello,
It seems you are facing problem with the ‘gwr’ function in MATLAB, the issue being the function is not able to accept input of type struct. If you go through the following documentation of Geographically weighted regression, it clearly shows that you require 4 inputs and a name value pair instead of struct. The inputs are
  1. x - n*m covariate matrix containing m covariates for n observations
  2. y - n*1 response vector containing n observations
  3. coors - n*2 coordinate matrix containing horizontal axis and vertical axis for n observations.
  4. bandwidth - scalar value indicating bandwidth parameter
  5. varargin - Name/Value pairs
Please visit the documentation to learn more regarding this,
