Produces Shiny applications for different types of popular functional data analyses. The functional data analyses are implemented in the refund package, then refund.shiny reads in the refund object and implements an object-specific set of plots based on the object class using S3.

It streamlines the evaluation of regression model
    assumptions, enhancing result reliability. With integrated tools for
    assessing key aspects like linearity, homoscedasticity, and more. It's
    a valuable asset for researchers and analysts working with regression
    models.

Implements regression calibration methods for correcting 
    measurement error in regression models using external or internal 
    reliability studies. Methods are described in Carroll, Ruppert, 
    Stefanski, and Crainiceanu (2006) "Measurement Error in Nonlinear 
    Models: A Modern Perspective" <doi:10.1201/9781420010138>.

Contains basic tools for visualizing, interpreting, and building regression models.  It has been designed for use with the book Introduction to Regression and Modeling with R by Adam Petrie, Cognella Publishers, ISBN: 978-1-63189-250-9.

We implement linear regression when the outcome of interest and some of the covariates are observed in two different datasets that cannot be linked, based on D'Haultfoeuille, Gaillac, Maurel (2022) <doi:10.3386/w29953>. The package allows for common regressors observed in both datasets, and for various shape constraints on the effect of covariates on the outcome of interest. It also provides the tools to perform a test of point identification. See the associated vignette <https://github.com/cgaillac/RegCombin/blob/master/RegCombin_vignette.pdf> for theory and code examples.

Regularised discriminant analysis functions. The classical regularised discriminant analysis proposed by Friedman in 1989, including cross-validation, of which the linear and quadratic discriminant analyses are special cases. Further, the regularised maximum likelihood linear discriminant analysis, including cross-validation. References: Friedman J.H. (1989): "Regularized Discriminant Analysis".
