Tidied datasets of confirmed exoplanets and their host stars,
    retrieved from NASA's Exoplanet Archive via the 'REXoplanets' package.
    Column names have been simplified for classroom use, with units baked
    into names where ambiguous. Intended as a companion dataset for
    introductory statistics teaching in the spirit of the 'ModernDive'
    textbook.

Pacote para a analise de experimentos havendo duas variaveis
    explicativas quantitativas e uma variavel dependente quantitativa. Os
    experimentos podem ser sem repeticoes ou com delineamento estatistico.
    Sao ajustados 12 modelos de regressao multipla e plotados graficos de
    superficie resposta (Hair JF, 2016) <ISBN:13:978-0138132637>.(Package
    for the analysis of experiments having two explanatory quantitative
    variables and one quantitative dependent variable. The experiments can
    be without repetitions or with a statistical design. Twelve multiple
    regression models are fitted and response surface graphs are plotted
    (Hair JF, 2016) <ISBN:13:978-0138132637>).

Provides a shiny-based front end (the 'ExPanD' app) and
    a set of functions for exploratory data analysis. Run as a web-based 
    app, 'ExPanD' enables users to assess the robustness of empirical evidence 
    without providing them access to the underlying data. You can export a 
    notebook containing the analysis of 'ExPanD' and/or use the functions of the 
    package to support your exploratory data analysis workflow. Refer to the 
    vignettes of the package for more information on how to use 'ExPanD' and/or 
    the functions of this package.

The amplitude-dependent exponential autoregressive (EXPAR) time series model, initially proposed by Haggan and Ozaki (1981) <doi:10.2307/2335819> has been implemented in this package. Throughout various studies, the model has been found to adequately capture the cyclical nature of datasets. Parameter estimation of such family of models has been tackled by the approach of minimizing the residual sum of squares (RSS). Model selection among various candidate orders has been implemented using various information criteria, viz., Akaike information criteria (AIC), corrected Akaike information criteria (AICc) and Bayesian information criteria (BIC). An illustration utilizing data of egg price indices has also been provided.
