This project presents a spatial analysis of public waste bin locations within The Vale, University of Birmingham. Using GIS-based methods in R, bin coordinates were mapped within a defined study area boundary to visualise their distribution and accessibility. The work demonstrates how spatial data and digital mapping can be used to assess infrastructure placement and support better understanding of urban service provision.

Formulación de la Frontera Eficiente, basada en la teoría de Harry Markowitz. Con la implementación en R se permite comprender la relación fundamental entre riesgo y rendimiento, destacando el papel de la diversificación en la optimización de carteras.

This document walks through the detection of heteroskedasticity in a multivariate OLS regression using the mtcars dataset. We estimate a regression of fuel efficiency on horsepower, weight, and displacement, visually inspect residual plots, run White's test via bptest(), and manually replicate the test statistic using an auxiliary regression and a chi-squared test.

This tutorial covers simulation from first principles: how R generates pseudo-random numbers, how to sample from the distributions that matter most in linguistics, how to assemble those draws into realistic datasets, and how to build the more advanced simulation workflows — fitting regression models for various distributions.
