Research project investigating the addition of confidence bounds to the drift diffusion model (DDM) in order to explain confidence ratings and their associated reaction times.

The RMCDA package is a comprehensive toolkit for Multi-Criteria Decision Analysis (MCDA), designed to facilitate the evaluation and ranking of alternatives based on multiple criteria. The package provides methods for implementing various MCDA techniques, including pairwise comparisons, partial-order analysis, and dominance-based decision rules.

Analysis and modelling of effort-based choice in economic decision-making

Balloon Analog Risk Task (PsychoPy) and data processing (R)

For files & code related to the EDI study ("Effort, Decision-making, and Interoception").

This is an online repository gathering all codes employed for the analyses presented in the paper (Torres-Martos Á et al. (2024)). The purpose of this repository is to allow researchers to reproduce the Machine Learning pipeline presented in the paper, as well as to adapt provided codes for the analyses of their own datasets.

Repository for example Hierarchical Drift Diffusion Model (HDDM) code using JAGS in R. These scripts provide useful examples for using JAGS with R2jags, the JAGS Wiener module, mixture modeling in JAGS, and Bayesian diagnostics in R.

Monte Carlo simulations to support decision making

This is my first R task during my Masters. The file contain UK Data Police in West Yorkshire about street criminal crimes from Jan 2020 - Sep 2021 and the objective of this task is to find interesting facts within this data.

Using R, I delve into two given datasets to conduct statistical analysis to help a company in its decision-making process.
