Fits the extended Vasicek single-factor credit loss model where
    the probability of default depends on macroeconomic covariates. Maximum
    likelihood estimates of all parameters, including asset value correlation,
    are obtained via closed-form probit-transformed OLS regression; see
    Mayorov (2026) <doi:10.2139/ssrn.6506378> for derivation.

Provides probability density, cumulative distribution,
    quantile, and random number generation functions for the Vasicek
    distribution. In addition, two functions are available for fitting
    Generalized Additive Models for Location, Scale and Shape introduced
    by Rigby and Stasinopoulos (2005,
    <doi:10.1111/j.1467-9876.2005.00510.x>). Some functions are written in
    'C++' using 'Rcpp', developed by Eddelbuettel and Francois (2011,
    <doi:10.18637/jss.v040.i08>).

Provides raster grid logic, operations that describe a discretized
 rectangular domain and do not require access to materialized data. Grids are
 arrays with dimension and extent, and many operations are functions of dimension
 only: number of columns, number of rows, or they are a combination of the
 dimension and the extent the range in x and the range in y in that order. Here
 we provide direct access to this logic without need for connection to any
 materialized data or formats. Grid logic includes functions that relate the cell
 index to row and column, or row and column to cell index, row, column or cell
 index to position. These methods are described in Loudon, TV, Wheeler, JF,
 Andrew, KP (1980)  <doi:10.1016/0098-3004(80)90015-1>, and implementations were
 in part derived from Hijmans R (2024) <doi:10.32614/CRAN.package.terra>.

An R client for the 'vatcheckapi.com' VAT number validation API. The API requires registration of an API key. Basic features are free, some require a paid subscription. You can find the full API documentation at <https://vatcheckapi.com/docs> .

Provides an interface to a 'HashiCorp' vault server over
  its http API (typically these are self-hosted; see
  <https://www.vaultproject.io>).  This allows for secure storage and
  retrieval of secrets over a network, such as tokens, passwords and
  certificates.  Authentication with vault is supported through
  several backends including user name/password and authentication via
  'GitHub'.
