qspec.analyze

The qspec.analyze module contains general purpose routines for (non)linear data fitting as well as a convenience class for multidimensional King plots. Wrappers for the scipy.optimize.curve_fit and the scipy.odr.odr routine, which use least-square optimization and orthogonal distance regression, respectively, extend their functionality and standardize their syntax. For fitting of a straight line, as needed in King-plots, the York algorithm and a Monte-Carlo (MC) method are implemented. In both cases, also a generalized version is implemented for fitting a straight line to data points in multiple dimensions, which are distributed according to independent multivariate normal distributions.
