A simulation and evaluation of earned value metrics to forecast the project duration [PDF]

open access: yesJournal of the Operational Research Society, 2007
In this paper, we extensively review and evaluate earned value (EV)-based methods to forecast the total project duration. EV systems have been set up to deal with the complex task of controlling and adjusting the baseline project schedule during execution, taking into account project scope, timed delivery and total project budget.

A comparison of financial duration models via density forecasts [PDF]

open access: yesInternational Journal of Forecasting, 2004
Using density forecast evaluation techniques, we compare the predictive performance of econometric specifications that have been developed for modeling duration processes in intra-day financial markets. The model portfolio encompasses various variants of the Autoregressive Conditional Duration (ACD) model and recently proposed dynamic factor models ...

A study on the minimum duration of training data to provide a high accuracy forecast for PV generation between two different climatic zones

open access: yesRenewable Energy, 2016
International audienceThis study focus on the minimum duration of training data required for PV generation forecast. In order to investigate this issue, the study is implemented on 2 PV installations: the first one in Guadeloupe represented for tropical ...

COVID-19 Pandemic: Duration and Epidemiological Forecast

open access: yesProblems of Particularly Dangerous Infections
The World Health Organization declared COVID-19 a pandemic on March 11, 2020. While in March 2022, i.e. approximately two years later, the global dominance of the phylogenetic variant of SARS-CoV-2 Omicron with its associated milder clinical course of the disease was registered, and therefore an epidemiological forecast was made about the onset of a ...

Modeling and Forecasting Persistent Financial Durations [PDF]

open access: yesSSRN Electronic Journal, 2012
This paper introduces the Markov-Switching Multifractal Duration (MSMD) model by adapting the MSM stochastic volatility model of Calvet and Fisher (2004) to the duration setting. Although the MSMD process is exponential $β$-mixing as we show in the paper, it is capable of generating highly persistent autocorrelation.

Forecasting the duration of short‐term deflation episodes [PDF]

open access: yesJournal of Forecasting, 2018
AbstractThe paper proposes a simulation‐based approach to multistep probabilistic forecasting, applied for predicting the probability and duration of negative inflation. The essence of this approach is in counting runs simulated from a multivariate distribution representing the probabilistic forecasts, which enters the negative inflation regime.

A stochastic approach to forecast project duration

open access: yesJournal of Management and Science, 2022
For executives who track projects on a complete / failed basis, at each phase of the project, the project completion date may be adjusted using only stochastic calculations in closed form. The proposed method to predict the final project duration may be interpreted intuitively.

Volatility Estimation and Forecasts Based on Price Durations [PDF]

open access: yesJournal of Financial Econometrics, 2021
Abstract We investigate price duration variance estimators that have long been neglected in the literature. In particular, we consider simple-to-construct non-parametric duration estimators, and parametric price duration estimators using autoregressive conditional duration specifications.

Forecasting the Remaining Duration of an Ongoing Solar Flare [PDF]

open access: yesSpace Weather, 2021
Abstract The solar X‐ray irradiance is significantly heightened during the course of a solar flare, which can cause radio blackouts due to ionization of the atoms in the ionosphere. As the duration of a solar flare is not related to the size of that flare, it is not directly clear how long those blackouts can persist.
