An application of Box–Jenkins transfer function analysis to consumption–income relationship in South Africa
(2005)Using a simple linear regression model for estimation could give misleading results about the relationship between Yt, and Xt, . Possible problems involve (1) feedback from the output series to the inputs, (2) omitted ... -
Characterising the long-term variability of blazars in leptonic models
(MDPI, 2019)Most research on blazar variability focuses on individual flares to explain acceleration and radiation mechanisms and improve on current models. These short-time events (being minutes, hours, or days) might not be ... -
A comprehensive power spectral density analysis of astronomical time series. I. The Fermi-LAT gamma-ray light curves of selected blazars
(IOP Publishing, 2020)We present the results of the Fermi-Large Area Telescope 10 yr long light curve (LC) modeling of selected blazars: six flat-spectrum radio quasars (FSRQs) and five BL Lacertae (BL Lacs), examined in 7, 10, and 14 day ... -
Radio frequency interference detection using machine learning
(IEEE, 2016)Radio frequency interference (RFI) has plagued radio astronomy which potentially might be as bad or worse by the time the Square Kilometre Array (SKA) comes up. RFI can be either internal (generated by instruments) or ...
