Abstract

Kertas ini membincangkan perbandingan antara kaedah LH momen dengan kaedah L momen. LH momen adalah L-momen umum yang berasaskan kepada gabungan linear bagi statistik tertib tinggi digunakan untuk dipadankan dengan ciri-ciri hujung taburan dan data ekstrim. Analisis terhadap data menggunakan penganggar LH momen bagi hujung atas taburan didapati LH lebih baik berbanding penganggar L momen. Perbandingan bagi gambarajah LH momen dan gambarajah L momen ke atas data juga menunjukkan bahawa taburan GEV dapat dipadankan dengan baik dengan nisbah LH momen berbanding dengan nisbah L momen. Katakunci: LH Moments; GEV; PWM; Gabungan Linear; Statistik Peringkat-Tinggi This paper discusses comparisons of the LH moments method with L moments method. LH moments, a generalization of L moments, based on linear combinations of higher-order statistics was introduced for charactering the upper part of distributions and larger events in data by Wang (1997). Analysis of observed data shows that using LH moments estimates of the upper part of distribution events are expected to be more reasonable than the L moments estimates. A comparison of the LH moment diagram and the L moment diagram of the data also shows that the GEV distribution describes the LH moment ratios better than the L moments. Keywords: LH moments; GEV; PWM; Linear Combination; Higher-Order Statistics
