Estimation of transition probabilities for the
	illness-death model and or the three-state progressive model.

Provide data generation and estimation tools for the truncated positive normal (tpn)
             model discussed in Gomez, Olmos, Varela and Bolfarine (2018) 
             <doi:10.1007/s11766-018-3354-x>, the slash tpn distribution discussed in Gomez, 
             Gallardo and Santoro (2021) <doi:10.3390/sym13112164>, the bimodal tpn distribution 
             discussed in Gomez et al. (2022) <doi:10.3390/sym14040665> and the flexible tpn model.

Regression models for temporal process responses with
        time-varying coefficient.

Density, distribution function, the quantile function, 
    random generation function, and maximum likelihood estimation.

Enables the acquisition of Korean financial market data, 
            designed to integrate seamlessly with the 'tidyquant' package.

Automates translating the instructions of 'iatgen' generated qsf
             (Qualtrics survey files) to other languages using either officially
             supported or user-supplied translations (for tutorial see Santos
             et al., 2023 <doi:10.17504/protocols.io.kxygx34jdg8j/v1>).

Plant ecologists often need to collect "traits" data
    about plant species which are often scattered among various
    databases: TR8 contains a set of tools which take care of
    automatically retrieving some of those functional traits data
    for plant species from publicly available databases (The Ecological Flora
    of the British Isles, LEDA traitbase, Ellenberg
    values for Italian Flora, Mycorrhizal intensity databases, BROT,
    PLANTS, Jepson Flora Project).
    The TR8 name, inspired by "car plates" jokes, was chosen since
    it both reminds of the main object of the package and is
    extremely short to type.

Efficient method for fitting nonparametric matrix trace regression model. The detailed description can be found in  C. Lee, L. Li, H. Zhang, and M. Wang (2021). Nonparametric Trace Regression via Sign Series Representation. <arXiv:2105.01783>. The method employs the aggregation of structured sign series for trace regression (ASSIST) algorithm.
