Hi, If I applies a variogram model into KrigeST fucntion, I get the error as follow: > DE_kriged <- krigeST(count~1, data=stfdf, newdata=stf,modelList=sumMetricVgm) Error in chol.default(A) : the leading minor of order 16 is not positive definiteIn addition: Warning message:In krigeST(count ~ 1, data = stfdf, newdata = stf, modelList = sumMetricVgm) : The spatio-temporal variogram model does not carry a time unit attribute: krisgeST cannot check whether the temporal distance metrics coincide.
I have tried applying different variogram models and different points. https://drive.google.com/open?id=0B3tdiSZ9hBj4dVZXOXItUjdrRlE Best,Ankur [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
