Spatial AUTOCorrelation

My professor tried his best to teach this spatial statistics concept to me but unfortunately he could not drive the point home. After five years Ranjeet made me realize that it was as simple as chossing an apple from a basket full of only apples. For people who dont know who Ranjeet is, he is my AUTO driver.

The simple fact that how he picks up another passenger for the same source and destination as mine made me understand what spatial auto-correlation is all about. That puts me in fix. Who is a better teacher ? my professor or Ranjeet ............. It is very simple I guess ....

who better than an Auto driver, can teach about AUTO-Correlation ?.
