Then, the methodological approaches revealed the use of LASSO to Linear Regression; LASSO for Multinomial Logistic Regression, Elastic Net Regression; Regression Tree, and Random Forest for the description of the pandemic in the Rio Grande do Sul. The results showed high accuracy in the identification of the relevant variables with a low error rate. Finally, it concluded that the three possible states of recovered, death, and recovering stage described using the machine learning methodology with a high degree of accuracy, attesting the adequacy of the measures adopted in the Rio Grande do Sul.
