Smoothing the Catalan tourism micro-data time series.

Manuel Artís Ortuño, Josep Lluís Carrion i Silvestre, Alex Costa Sáenz de San Pedro, Jordi Suriñach Caralt (2002)

Qüestiió

Similarity:

In this paper we propose a method for smoothing the Catalan tourism time series between 1997 and 2000. These time series, built upon a micro database drawn from a survey conducted by the Statistical Institute of Catalonia, are somewhat volatile due, it would seem, to the incomplete nature of the information. The application of a smoothing procedure based on the combination of classical techniques and weighted moving averages allows us to overcome the problems caused by this lack of information...

On the properties typical of economic time series.

Arthur B. Treadway (1984)

Qüestiió

Similarity:

This paper summarizes the results of econometric time-series analysis performed by the author and colleagues over the last seven years, using the Box-Jenkins approach in interaction with Economic Theory. Typical univariate properties, typical data anomalies and typical relationships are described. Common practice in Econometrics is criticized and certain aspects of Economic Theory are discussed.

Data mining techniques using decision tree model in materialised projection and selection view.

Y. W. Teh (2004)

Mathware and Soft Computing

Similarity:

With the availability of very large data storage today, redundant data structures are no longer a big issue. However, an intelligent way of managing materialised projection and selection views that can lead to fast access of data is the central issue dealt with in this paper. A set of implementation steps for the data warehouse administrators or decision makers to improve the response time of queries is also defined. The study concludes that both attributes and tuples, are important...
