C The fit command: mathematical details

Details of the fit command

In this section, the mathematical details of the workings of the fit command are described. This may be of interest in diagnosing its limitations, and also in understanding the various quantities that it outputs after a fit is found. This discussion must necessarily be a rather brief treatment of a large subject; for a fuller account, the reader is referred to D.S. Sivia’s Data Analysis: A Bayesian Tutorial.
