Statistical Methods - For Mineral Engineers __exclusive__

Pierre Gy dedicated his life to the statistics of sampling. His fundamental law is that the sampling variance (apart from geological variance) is inversely proportional to the sample mass.

Y=β0+β1X1+β2X2+…+βnXn+ϵcap Y equals beta sub 0 plus beta sub 1 cap X sub 1 plus beta sub 2 cap X sub 2 plus … plus beta sub n cap X sub n plus epsilon is the process response, Xicap X sub i are the operational variables, βibeta sub i are the calculated coefficients, and Statistical Methods For Mineral Engineers
