Forecasting telecommunications data with Autoregressive Integrated Moving Average models [PDF]

open access: yes2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS), 2015
Forecasting of telecommunication data find difficult according to International Telecommunication Union (ITU) due to uncertainty involved and the continuous growth of data in telecommunication markets as it helps them in planning and determining their networks. So, there is a need of good forecasting model to predict the future.

On Long Memory Origins and Forecast Horizons [PDF]

open access: yesJournal of Forecasting (2020) DOI: 10.1002/for.2651, 2017
Most long memory forecasting studies assume that the memory is generated by the fractional difference operator. We argue that the most cited theoretical arguments for the presence of long memory do not imply the fractional difference operator, and assess the performance of the autoregressive fractionally integrated moving average $(ARFIMA)$ model when ...

Modeling of covid-19 in Indonesia using vector autoregressive integrated moving average

open access: yes, 2021
A phenomenon of coronavirus became a big deal around the world at the end of December 2019. To find out how deadly the disease is, we can use the Case Fatality Rate (CFR), which provides the ratio number of deaths due to covid-19 between founded cases ...

Statistical inference for ARTFIMA time series with stable innovations [PDF]

open access: yesarXiv, 2021
Autoregressive tempered fractionally integrated moving average with stable innovations modifies the power-law kernel of the fractionally integrated time series model by adding an exponential tempering factor. The tempered time series is a stationary model that can exhibits semi-long-range dependence. This paper develops the basic theory of the tempered

Asymptotic properties of autoregressive integrated moving average processes

open access: yesStochastic Processes and their Applications, 1975
AbstractIn this paper we study the asymptotic behavior of so-called autoregressive integrated moving average processes. These processes constitute a large class of stochastic difference equations which includes among many other well-known processes the simple one-dimensional random walk. They were dubbed by G.E.P. Box and G.M. Jenkins who found them to

Modeling and predicting measured response time of cloud-based web services using long-memory time series [PDF]

open access: yesThe Journal of Supercomputing, February 2015, Volume 71, Issue 2, pp 673-696, 2016
Predicting cloud performance from user's perspective is a complex task, because of several factors involved in providing the service to the consumer. In this work, the response time of 10 real-world services is analyzed. We have observed long memory in terms of the measured response time of the CPU-intensive services and statistically verified this ...

Immunity Debt for Seasonal Influenza After the COVID‐19 Pandemic and as a Result of Nonpharmaceutical Interventions: An Ecological Analysis and Cohort Study

open access: yesAdvanced Science, EarlyView.
This study provides support for the immunity debt hypothesis, revealing a 131.72% increase in influenza rates during winter and a 161.23% rise in summer, 1 year following the global easing of COVID‐19 restrictions. This study offers empirical evidence of immunity debt on a global level, highlighting the importance of incorporating this concept into the
