The app has a fairly easy initial functionality, it is responsible for reviewing the different possible rgression models taking the different categories that the iris data has, looking for the relationships between Sepal width and Petal width, it is published in the following link: https://serebe.shinyapps.io/Coursera_App_IRIS/?_ga=2.35943272.997301519.1658892862-1595453304.1658892862 and this another link for github: https://github.com/serebe/APP_Coursera
