ModEst - Model estimation package for inverse problems The flagship function for this package is modest.nllstsq.nonlin_lstsq, which is a nonlinear least-squares solver. It performs the same operations as scipy.optimize.curve_fit and includes a great deal of regularization options. See the documentation for nonlin_lstsq for more information This package also includes a package for generating a Tikhonov regularization matrix based on connectivity of model parameters and it includes a Kalman filtering class. There is currently little documentation for these features. Install ModEst with the shell command "python setup.py install"
