Use numerical optimization to fit ordinary differential equations (ODEs) to time series data to examine the dynamic relationships between variables or the characteristics of a dynamical system. It can now be used to estimate the parameters of ODEs up to second order, and can also apply to multilevel systems. See <https://github.com/yueqinhu/defit> for details.

Simple functions to deflate nominal Brazilian Reais using several popular price indexes downloaded from the Brazilian Institute for Applied Economic Research.

Implements the 'deflist' class, a read-only list-like object that accesses its elements via a function.
    The 'deflist' class can be used to model deferred access to data or computations by routing indexed list access to a function.
    This approach is particularly useful when sequential list-like access to data is required but holding all the data in memory at once is not feasible.
    The package also provides utilities for memoisation and caching to optimize access to frequently requested elements.

Implements two out-of box classifiers presented in <doi:10.48550/arXiv.2112.01063> for 
    distinguishing forest and non-forest terrain images. Under these algorithms, there are 
    frequentist approaches: one parametric, using stable distributions, and another one- 
    non-parametric, using the squared Mahalanobis distance. The package also contains functions for 
    data handling and building of new classifiers as well as some test data set.

Methods for fitting nonstationary Gaussian process models by spatial deformation, as introduced by Sampson and Guttorp (1992) <doi:10.1080/01621459.1992.10475181>, and by dimension expansion, as introduced by Bornn et al. (2012) <doi:10.1080/01621459.2011.646919>. Low-rank thin-plate regression splines, as developed in Wood, S.N. (2003) <doi:10.1111/1467-9868.00374>, are used to either transform co-ordinates or create new latent dimensions.
