Novel SIMEX algorithm for autoregressive models to estimate AGN variability
Felipe Elorrieta, Wilfredo Palma, Susana Eyheramendy +2
The origin of the variability in accretion disks of active galactic nuclei (AGN) is still unknown, but its behavior can be characterized by modeling the time series of optical wave…
Online estimation methods for irregular autoregressive models
Felipe Elorrieta, Lucas Osses, Matias Cáceres +2
In the last decades, due to the huge technological growth observed, it has become increasingly common that a collection of temporal data rapidly accumulates in vast amounts. This p…
A Novel First-Order Autoregressive Moving Average Model to Analyze Discrete-Time Series Irregularly Observed
Cesar Ojeda, Wilfredo Palma, Susana Eyheramendy +1
A novel first-order autoregressive moving average model for analyzing discrete-time series observed at irregularly spaced times is introduced. Under Gaussianity, it is established…
An irregularly spaced first-order moving average model
Cesar Ojeda, Wilfredo Palma, Susana Eyheramendy +1
A novel first-order moving-average model for analyzing time series observed at irregularly spaced intervals is introduced. Two definitions are presented, which are equivalent under…
Novel bivariate autoregressive model for predicting and forecasting irregularly observed time series
Felipe Elorrieta, Susana Eyheramendy, Wilfredo Palma +1
In several disciplines it is common to find time series measured at irregular observational times. In particular, in astronomy there are a large number of surveys that gather infor…
The Automatic Learning for the Rapid Classification of Events (ALeRCE) Alert Broker
F. Förster, G. Cabrera-Vives, E. Castillo-Navarrete +37
We introduce the Automatic Learning for the Rapid Classification of Events (ALeRCE) broker, an astronomical alert broker designed to provide a rapid and self--consistent classifica…
