Hi all, My question is on cross-variogram calculation and specifically: I have a cross variogram that shows negative spatial correlation but there is a nugget effect which is positive. Another crossvariogram shows positive spatial correlation and the nugget effect is negative. My question is: what does the nugget effect imply in those cases and is it posible for two variables to present negative correlation at small distances and positive correlation at larger distances?
