Abstract

Kondisi perekonomian suatu negara dapat mengalami suatu fluktuasi dari tahun ke tahun yang dipengaruhi oleh faktor internal maupun faktor eksternal perekonomian itu sendiri, sehingga ketidakstabilan yang dirasakan dapat mem-pengaruhi perilaku para pasar modal dalam menganalisis dan memprediksi pen-dapatannya. Data Time series khususnya pada kasus data bursa saham, data keuangan, dan data ekonomi, umumnya mempunyai model tertentu karena adanya suatu kondisi heteroskedastisitas, hal ini disebabkan adanya sifat volatilitas dalam datanya. Salah satu model yang sesuai untuk mengatasi masalah tersebut adalah model ARCH-GARCH. Namun dalam kenyataanya model ARCH-GARCH tersebut tidak mampu mendeteksi pergerakan fluktuasi harga saham yang naik turun sehingga ada kesulitan bagi seorang investor untuk melakukan tindakan membeli atau menjual terhadap suatu saham. Untuk mengatasi masalah tersebut, maka akan digunakan model EGARCH yang merupakan perluasan dari model GARCH. Model EGARCH selain memperhatikan tinggi rendahnya fluktuasi dari return juga dapat mendeteksi nilai positif-negatif dari return. Hasil yang diperoleh menunjukkan bahwa pemodelan data dengan memperhatikan fluktuasi yang bernilai positif-negatif dan tinggi-rendah menghasilkan model yang lebih baik dibandingkan dengan model yang memperhatikan fluktuasi yang tinngi-rendah.

Abstract

The calculus have introduce the real functions namely for all functions to map real number to the real number. Now, the explanation it not only to real number but the mapping of norm space that is a linier transformations, namely the mathematical sentences with the mapping of a vector space to the others. The purpose of this research are how to know the requirements a infinite matrices in order to be a like as transformations in the sequences space is the sequences space c0 to c0. Matrices An x m can be looked as linier transformation of Rm to Rn. So the functions can map to point (x1, x2, x3, …, xm) at Rm to a point (y1, y2, y3,…, yn) at Rn. The similarly, a matrices can be looked as linier transformation of the sequences space to the others provided that line and coloum matrices that infinite elements. In this case, matrices map the sequences (x1, x2, x3, …) to the sequences (y1, y2, y3,…). This matrices is a infinite matrices. There for, the infinite matricres must fulfill several requirements in order be linier transformations of the sequences space to the certain sequences space, that is the infinite matrices A = (ank)n≥1 (k certain) with a finite suprimum can be linier transformation of the sequences c0 to c0.Key Words: The matrices of transformation, Banach space, Hilbert space, the sequences space c0 to c0.
