I’m Miguel Ángel, a Data Science student at Universidad del Norte (Barranquilla, Colombia). This RPubs space gathers documents I’ve created throughout my degree, including coursework reports, class notes, and project write-ups, along with a few personal projects. The focus is on applied statistics, exploratory data analysis, data visualization, and machine learning, mostly using R and Quarto.
Because my studies are based in Colombia, where Spanish is the primary language of instruction, most posts are in Spanish. You’ll also find some publications in English. Each document notes its language at the beginning, and whenever possible I include code and data so the work is reproducible.
I’m still learning and not yet an expert, so these pieces may not be perfect.
