EVALUATING THE IMPACT OF DATA.GOV.RO ON THE ACADEMIC RESEARCH [PDF]
Analele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie, 2022 In the context of the digital revolution, data is the most valuable resource which gains in value the more it is used. Freely available open source data and institutional data repositories encourage and connect, both academia and industry.

Time series analysis in environmental epidemiology: challenges and considerations
International Journal of Occupational Medicine and Environmental Health, 2023 In environmental epidemiology, time series analyses represent a widely used statistical tool. However, though being commonly used, there is soften confusion regarding the specific requirements, such as which link function might be most appropriate, when ...

Contracts, Business Models and Barriers to Investing in Low Temperature District Heating Projects
Applied Sciences, 2019 Approximately 1.2 EJ of energy are potentially available for recovery each year from urban heat sources in the EU. This corresponds to more than 10 percent of the EU’s total energy demand for heat and hot water.

Targeted model evaluations for climate services: A case study on heat waves in Bangladesh
Climate Risk Management, 2020 Though not a sufficient condition, the ability to reproduce key elements of climate variability over the historical record should be a minimum requirement for placing any confidence in a model’s climate forecasts or projections of climate change.

A Parametric Factor Model of the Term Structure of Mortality
Econometrics, 2019 The prototypical Lee–Carter mortality model is characterized by a single common time factor that loads differently across age groups. In this paper, we propose a parametric factor model for the term structure of mortality where multiple factors are

TIME Series Analysis Using Copula Gauss And Ar(1)-n.garch(1,1) [PDF]
, 2016 In this case, the Gaussian Copula is used to connect the data that correlates with the time and with other data sets. Most often, practitioners rely only on the linear correlation to describe the degree of dependence between two or more variables; an ...

Hybrid Time Series Method for Long-Time Temperature Series Analysis
Discrete Dynamics in Nature and Society, 2021 This paper combines discrete wavelet transform (DWT), autoregressive moving average (ARMA), and XGBoost algorithm to propose a weighted hybrid algorithm named DWTs-ARMA-XGBoost (DAX) on long-time temperature series analysis.

Mandelbrot's Stochastic Time Series Models
Earth and Space Science, 2019 I survey and illustrate the main time series models that Mandelbrot introduced into time series analysis in the 1960s and 1970s. I focus particularly on the members of the additive fractional stable family including Lévy flights and fractional Brownian ...

Demonstrating the value of larger ensembles in forecasting physical systems
Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 Ensemble simulation propagates a collection of initial states forward in time in a Monte Carlo fashion. Depending on the fidelity of the model and the properties of the initial ensemble, the goal of ensemble simulation can range from merely quantifying ...
