Quick-count MX

In Mexico quick-counts take place whenever major elections take place. For the quick-counts a probabilistic sample of polling stations is selected in advance and estimates are presented in the election night. The complete samples are rarely available to publish the results in a timely manner hence the results are announced using partial samples which have biases. We developed a Bayesian hierarchical model that includes demographic and geographic covariates, the model reduces the biases associated to such covariates. The model was used, among others, for the [2018 quick-count]( organized by the electoral authority. [Here]( we explain the model in detail and [here]( is an R package with the model implementation, and [here]( is a published paper with the methodology for one of the models we used.

Exploratory Data Analysis and Survey Sampling (Spanish)

I taught a course in Exploratory Data Analysis and Survey Sampling for bachelors in Mathematics and Actuarial Sciences at ITAM. I am in the process of uploading the material (developed by Felipe Gonzalez).
