Estimation Quotes
Were I to remove the veil, all would recognize Me as their Best Beloved, and no one would deny Me. Let not this assertion astound Your Majesty; inasmuch as a true believer in the unity of God who keepeth his eyes directed towards Him alone, will regard aught else but Him as utter nothingness. I swear by God! I seek no earthly goods from thee, be it as much as a mustard seed. Indeed, to possess anything of this world or of the next would, in My estimation, be tantamount to open blasphemy. For it ill beseemeth the believer in the unity of God to turn his gaze to aught else, much less to hold it in his possession.

First of all I want to remind you of the essential features of models. In my opinion they are: (i) drawing up a list of the variables to be considered; (ii) drawing up a list of the equations or relations the variables have to obey and (iii) testing the validity of the equations, which implies the estimation of their coefficients, if any. As a consequence of especially (iii) we may have to revise (i) and (ii) so as to arrive at a satisfactory degree of realism of the theory embodied in the model. Then, the model may be used for various purposes, that is, for the solution of various problems. The advantages of models are, on one hand, that they force us to present a "complete" theory by which I mean a theory taking into account all relevant phenomena and relations and, on the other hand, the confrontation with observation, that is, reality. Of course these remarks are far from new.
