AI-GEOSTATS: pseudo cross variogram: h=0

[Peijun Li]

Dear List,   I recently use the pseudo cross variogram (PCV) for remote sensing applications. However, I don’t know what does the PCV reflect when lag h=0? As we know, when lag h=0, the (univariate) variogram reflects the nugget effect. Is there any similar meaning for PCV? Could you give me some references related to PCV?   Thanks in advance for reply.   Peijun Li Peking University
