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)
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'.
Deal with Check Outputs
Deal with packages 'check' outputs and reduce the risk of rejection by 'CRAN' by following policies.
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.

Analysing 'SNP' and 'Silicodart' Data Generated by Genome-Wide Restriction Fragment Analysis
Facilitates the analysis of SNP (single nucleotide polymorphism)
and silicodart (presence/absence) data. 'dartR.popgen' provides a suit of
functions to analyse such data in a population genetics context. It provides
several functions to calculate population genetic metrics and to study
population structure. Quite a few functions need additional software to be
able to run (gl.run.structure(), gl.blast(), gl.LDNe()). You find detailed description
in the help pages how to download and link the packages so the function can
run the software. 'dartR.popgen' is part of the the 'dartRverse' suit of packages.

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,
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.

Analysing SNP Data to Identify Sex-Linked Markers
Identifies, filters and exports sex linked markers using 'SNP' (single nucleotide polymorphism) data. To install the other packages, we recommend to install the 'dartRverse' package, that supports the installation of all packages in the 'dartRverse'. If you want understand the applied rational to identify sexlinked markers and/or want to cite 'dartR.sexlinked', you find the information by typing citation('dartR.sexlinked') in the console.
Time Series Prediction with Integrated Tuning
Time series prediction is a critical task in data analysis, requiring not only the selection of appropriate models, but also suitable data preprocessing and tuning strategies.
TSPredIT (Time Series Prediction with Integrated Tuning) is a framework that provides a seamless integration of data preprocessing, decomposition, model training, hyperparameter optimization, and evaluation.
Unlike other frameworks, TSPredIT emphasizes the co-optimization of both preprocessing and modeling steps, improving predictive performance.
It supports a variety of statistical and machine learning models, filtering techniques, outlier detection, data augmentation, and ensemble strategies.
