Solve a system of nonlinear equations using a Broyden or a Newton method
             with a choice of global strategies such as line search and trust region.
             There are options for using a numerical or user supplied Jacobian,
             for specifying a banded numerical Jacobian and for allowing
             a singular or ill-conditioned Jacobian.

Interface to the open location server API of 'Publieke Diensten Op de Kaart' (<http://www.pdok.nl>). It offers geocoding, address suggestions and lookup of geographical objects. Included is an utility function for displaying leaflet tiles restricted to the Netherlands.

Six growth models are fitted using non-linear least squares. These are the Richards, the 3, 4 and 5 parameter logistic, the Gompetz and the Weibull growth models.

Models for non-linear time series analysis and causality detection. The main functionalities of this package consist of an implementation of the classical causality test (C.W.J.Granger 1980) <doi:10.1016/0165-1889(80)90069-X>,  and a non-linear version of it based on feed-forward neural networks. This package contains also an implementation of the Transfer Entropy <doi:10.1103/PhysRevLett.85.461>, and the continuous Transfer Entropy using an approximation based on the k-nearest neighbors <doi:10.1103/PhysRevE.69.066138>. There are also some other useful tools, like the VARNN (Vector Auto-Regressive Neural Network) prediction model, the Augmented test of stationarity, and the discrete and continuous entropy and mutual information.

Create and manipulate numeric list ('nlist') objects.  An
    'nlist' is an S3 list of uniquely named numeric objects.  An numeric
    object is an integer or double vector, matrix or array.  An 'nlists'
    object is a S3 class list of 'nlist' objects with the same names,
    dimensionalities and typeofs.  Numeric list objects are of interest
    because they are the raw data inputs for analytic engines such as
    'JAGS', 'STAN' and 'TMB'.  Numeric lists objects, which are useful for
    storing multiple realizations of of simulated data sets, can be
    converted to coda::mcmc and coda::mcmc.list objects.
