Inference and Forecasting for Fractional Autoregressive Integrated Moving Average Models, with an application to US and UK in ation
نویسندگان
چکیده
We discuss computational aspects of likelihood-based speci cation, estimation, inference, and forecasting of possibly nonstationary series with long memory. We use the arfima(p; d; q) model with deterministic regressors and we compare sampling characteristics of approximate and exact rst-order asymptotic methods. We extend the analysis using a higher-order asymptotic method, suggested by Cox and Reid (1987). EÆcient computation and simulation allow us to apply parametric bootstrap inference as well. We investigate the relevance of the di erences between the methods for the time-series analysis of monthly core consumer price in ation in the US and quarterly overall consumer price in ation in the UK. We concentrate on (stationarity) tests for the order of integration and on inference for out-of-sample forecasts of the price level. * Econometric Institute, Erasmus University Rotterdam, The Netherlands. ** NuÆeld College, New Road, Oxford OX1 1NF, UK.

AN EXTENDED FUZZY ARTIFICIAL NEURAL NETWORKS MODEL FOR TIME SERIES FORECASTING
Improving time series forecastingaccuracy is an important yet often difficult task.Both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. In this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...
متن کاملComparison of autoregressive integrated moving average (ARIMA) model and adaptive neuro-fuzzy inference system (ANFIS) model
Proper models for prediction of time series data can be an advantage in making important decisions. In this study, we tried with the comparison between one of the most useful classic models of economic evaluation, auto-regressive integrated moving average model and one of the most useful artificial intelligence models, adaptive neuro-fuzzy inference system (ANFIS), investigate modeling procedur...
متن کاملForecasting Gold Price Changes: Application of an Equipped Artificial Neural Network
The forecast of fluctuations and prices is the major concern in financial markets. Thus, developing an accurate and robust forecasting decision model is critically favorable to the investors. As gold has shown a special capability to smooth inflation fluctuations, governors use gold as a price controlling lever. Thus, more information about future gold price trends will help to make the firm de...
متن کاملApplication of a Statistical Model to Forecast Drowning Deaths in Iran
Background/aim: One of the indicators for measuring the development of a country is its death rate caused by accidents and disasters. Every year, many people in Iran are drowned for various reasons. The aim of this study was to predict the trend of drowning mortality in Iran using statistical models. Method: This research was a longitudinal study using time-series data of drowning deaths obta...
