Spurious deterministic seasonality and autocorrelation corrections with quarterly data: Further Monte Carlo results [PDF]
Following recent work of Franses, Hylleberg and Lee (FHL), this paper analyses the consequences of fitting a deterministic seasonal model to a quarterly time series which can be (at least approximately) described by a seasonal unit root(s) model. Besides the distribution of the coefficient of determination, the empirical distributions of two commonly ...

Prediction of Airport Acoustical Noise by Deterministic Decomposition and Seasonal ARIMA Techniques
2018In this paper a time series of hourly equivalent noise levels acquired near the international airport of Nice, France, is analysed. Two different techniques are proposed to model and forecast the time series: deterministic decomposition and seasonal autoregressive moving average.

Mathematical Methods in the Applied Sciences
ABSTRACTIn this research, we study numerical solutions for a deterministic fractional seasonal influenza model. Using seasonal fluctuations and population dynamics, the model, which was formulated using the definition of Caputo fractional calculus, provides a nuanced view of the dynamics of the influenza transmission.

Testing for unit roots in time series with nearly deterministic seasonal variation
Econometric Reviews, 1997This paper addresses the problem of testing for the presence of unit autoregressive roots in seasonal time series with negatively correlated moving average components. For such cases, many of the commonly used tests are known to have exact sizes much higher than their nominal significance level.

Deterministic Seasonal Volatility in a Small and Integrated Stock Market: The Case of Sweden. [PDF]
Using daily data for the Swedish stock market for almost the last two decades no distinct and firm deterministic seasonal pattern for the conditional volatility for the Swedish stock market has been found. The daily turnover in the Swedish stock market has an impact on and eliminates to some extent seasonal patterns in conditional volatility. The daily
