Tool for Statistical and Environmental Analysis R package GREENREG version 0.1.2 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. Developed as part of an undergraduate thesis at the Universidad Autónoma Chapingo, under the supervision of Dr. Julio César Buendía Espinoza (thesis advisor), with the participation of the thesis committee: Diego Ernesto Lira González (secretary), Israel Lerma Serna (member), Juan Uriel Avelar Roblero (alternate), and Elisa del Carmen Martínez Ochoa (alternate). Methods for regression and time series are based on Montgomery, Peck & Vining (2021, Introduction to Linear Regression Analysis, 6th ed., Wiley, ISBN:978-1119578727) and Box, Jenkins, Reinsel & Ljung (2015, Time Series Analysis: Forecasting and Control, 5th ed., Wiley, ISBN:978-1118675021).
