Estimating Counts Through an Average Rounded to the Nearest Non-negative Integer and its Theoretical & Practical Effects
Roberto Rivera, Axel Cortes-Cubero, Roberto Reyes-Carranza +1
In practice, the use of rounding is ubiquitous. Although researchers have looked at the implications of rounding continuous random variables, rounding may also be applied to functi…
Modeling Excess Deaths After a Natural Disaster with Application to Hurricane Maria
Roberto Rivera, Wolfgang Rolke
Estimation of excess deaths due to a natural disaster is an important public health problem. The CDC provides guidelines to fill death certificates to help determine the death toll…
A Low Rank Gaussian Process Prediction Model for Very Large Datasets
Roberto Rivera
Spatial prediction requires expensive computation to invert the spatial covariance matrix it depends on and also has considerable storage needs. This work concentrates on computati…
A Dynamic Linear Model to Forecast Hotel Registrations in Puerto Rico Using Google Trends Data
Roberto Rivera
Recently, studies have used search query volume (SQV) data to forecast a given process of interest. However, Google Trends SQV data comes from a periodic sample of queries. As a re…
Spatial prediction variance estimation based on covariance penalty
Roberto Rivera, Wendy Meiring
In practice rarely (if ever) is the spatial covariance known in spatial prediction problems. Often, prediction is performed after estimated spatial covariance parameters are plugge…
