EVDHM-ARIMA-Based Time Series Forecasting Model and Its Application for COVID-19 Cases
نویسندگان
چکیده
The time-series forecasting makes a substantial contribution in timely decision-making. In this article, recently developed eigenvalue decomposition of Hankel matrix (EVDHM) along with the autoregressive integrated moving average (ARIMA) is applied to develop model for nonstationary time series. Phillips–Perron test (PPT) used define nonstationarity EVDHM over series decompose it into respective subcomponents and reduce nonstationarity. ARIMA-based designed forecast future values each subcomponent. subcomponent are added get final output values. optimized value ARIMA parameters obtained using genetic algorithm (GA) minimum Akaike information criterion (AIC). Model performance evaluated by estimating daily new cases recent pandemic disease COVID-19 India, USA, Brazil. high efficacy proposed method convinced results.

Forecasting time series data is an important subject in economics, business, and finance. Traditionally, there are several techniques to effectively forecast the next lag of time series data such as univariate Autoregressive (AR), univariate Moving Average (MA), Simple Exponential Smoothing (SES), and more notably Autoregressive Integrated Moving Average (ARIMA) with its many variations. In par...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
