  • Spatial Weighted Matrix containing Island

    Dear All,

    For my spatial regression I am creating spatial matrix based on contiguity and sphere normalization.
    I found there are 33 island from 514 observation that I have.
    This is the command that I use :
    Code:
    spmatrix create contiguity WC
    However, I still want to use this matrix for the spatial regression as these observations are very isolated. I think it is fine to ignore their spillover impact.
    My question are...
    When I run the spregress using that matrix, what happened to those 33 islands?
    Will it be excluded in the regression?
    Can I do spatial regression using matrix with island?

    Please help me understand this. Thank you
Working...
