%description
Provides a set of accessible and automated functions to apply statistical
models such as Simple Linear Regression (RLS, from the Spanish 'Regresión
Lineal Simple'), Multiple Linear Regression (RLM, from the Spanish
'Regresión Lineal Múltiple'), Generalized Linear Models (GLM), and time
series analysis through Autoregressive Integrated Moving Average (ARIMA)
models. Designed to support teaching at the Universidad Autónoma Chapingo,
it facilitates results interpretation and assumption validation through
automatic graphical diagnostics. Methods for regression and time series
are based on Montgomery et al. (2021, ISBN:978-1119570141) and Box &
Jenkins (1970, ISBN:978-0816211043).
