dear list members!
i am try to use structural equation modeling (SEM) for ore reserve estimation. i have taken cordinate system (x,y,z) as an independent variable and mineral constituent ( for limestone mines cao, al2o3, fe2o3 and sio2) as the dependent variable. and i have got better results than ANN applied result. it gives MSE is very less(.0012) and R value is 0.97.
now my question is that the approach which i have used is it acceptabe for the geostatistical point of view.
