Incorporate Expert Opinion with Parametric Survival Models
Enables users to incorporate expert opinion with parametric survival analysis using a Bayesian or frequentist approach. Expert Opinion can be provided on the survival probabilities at certain time-point(s) or for the difference in mean survival between two treatment arms. Please reference it's use as Cooney, P., White, A. (2023)
Estimating Aboveground Biomass and Its Uncertainty in Tropical Forests
Contains functions for estimating above-ground biomass/carbon and its uncertainty in tropical forests. These functions allow to (1) retrieve and correct taxonomy, (2) estimate wood density and its uncertainty, (3) build height-diameter models, (4) manage tree and plot coordinates, (5) estimate above-ground biomass/carbon at stand level with associated uncertainty.

Estimate Quantiles Curves
Non-parametric methods as local normal regression, polynomial local regression and penalized cubic B-splines regression are used to estimate quantiles curves. See Fan and Gijbels (1996)
Fuzzy and Non-Fuzzy Classifiers
It provides classifiers which can be used for discrete variables and for continuous variables based on the Naive Bayes and Fuzzy Naive Bayes hypothesis. Those methods were developed by researchers belong to the 'Laboratory of Technologies for Virtual Teaching and Statistics (LabTEVE)' and 'Laboratory of Applied Statistics to Image Processing and Geoprocessing (LEAPIG)' at 'Federal University of Paraiba, Brazil'. They considered some statistical distributions and their papers were published in the scientific literature, as for instance, the Gaussian classifier using fuzzy parameters, proposed by 'Moraes, Ferreira and Machado' (2021)
Deal with Check Outputs
Deal with packages 'check' outputs and reduce the risk of rejection by 'CRAN' by following policies.
Install and Load the 'dartRverse' Suits of Packages
Provides a single function that supports the installation of all packages belonging to the 'dartRverse'. The 'dartRverse' is a set of packages that work together to analyse SNP (single nuclear polymorphism) data. All packages aim to have a similar 'look and feel' and are based on the same type of data structure ('genlight'), with additional metadata for loci and individuals (samples). For more information visit the 'GitHub' pages < https://github.com/green-striped-gecko/dartRverse>.
Applying Landscape Genomic Methods on 'SNP' and 'Silicodart' Data
Provides landscape genomic functions to analyse 'SNP' (single nuclear polymorphism) data, such as least cost path analysis and isolation by distance. Therefore each sample needs to have coordinate data attached (lat/lon) to be able to run most of the functions. 'dartR.spatial' is a package that belongs to the 'dartRverse' suit of packages and depends on 'dartR.base' and 'dartR.data'.
Geolocalização De Endereços Brasileiros (Geocoding Brazilian Addresses)
Método simples e eficiente de geolocalizar dados no Brasil. O pacote é baseado em conjuntos de dados espaciais abertos de endereços brasileiros, utilizando como fonte principal o Cadastro Nacional de Endereços para Fins Estatísticos (CNEFE). O CNEFE é publicado pelo Instituto Brasileiro de Geografia e Estatística (IBGE), órgão oficial de estatísticas e geografia do Brasil. (A simple and efficient method for geolocating data in Brazil. The package is based on open spatial datasets of Brazilian addresses, primarily using the Cadastro Nacional de Endereços para Fins Estatísticos (CNEFE), published by the Instituto Brasileiro de Geografia e Estatística (IBGE), Brazil's official statistics and geography agency.)
Sequential Outlier Identification for Model-Based Clustering
Sequential outlier identification for Gaussian mixture models using
the distribution of Mahalanobis distances. The optimal number
of outliers is chosen based on the dissimilarity between the theoretical and
observed distributions of the scaled squared sample Mahalanobis distances.
Also includes an extension for Gaussian linear cluster-weighted models using
the distribution of studentized residuals.

Fits Expectile Regression for Panel Fixed Effect Model
Fits the Expectile Regression for Fixed Effect (ERFE)
estimator. The ERFE model extends the within-transformation strategy
to solve the incidental parameter problem within the expectile
regression framework. The ERFE model estimates the regressor effects
on the expectiles of the response distribution. The ERFE estimate
corresponds to the classical fixed-effect within-estimator when the
asymmetric point is 0.5. The paper by Barry, Oualkacha, and
Charpentier (2021,
