I would even go one step further - depreciate guessParametersErrors() - rename this method as getParametersStandardDeviation(), since the implemented formula seems to be the accepted estimate for the sd of the optimized parameters. > > Then, to further disambiguate, we could add a > double[] getSigma() > method that will in effect return the (sqrt of the) diagonal elements of the > covariance matrix. > I'm not sure, now. Indeed, sigma would suggest that the returned value is the standard deviation, which it is not (see above). I must check that the square root of the diagonal elements of the covariance matrix (with no prefactor) are really meaningful from a statistical point of view. If they are not, I suggest we do not provide any accessor. What do you think?
