Abstract

Generalized Linear Model (GLM) merupakan perluasan dari model regresi umum untuk variabel respon yang mengikuti distribusi keluarga eksponensial, termasuk distribusi normal, binomial, poisson, negative binomial, eksponensial, dan gamma. Jika variabel respon bersifat diskrit dan mengikuti distribusi Poisson, maka model regresi Poisson dapat digunakan untuk pembentukan model. Namun, dalam penerapannya, sering kali terjadi overdispersi, di mana varians lebih besar dari rata-rata. Overdispersi dalam regresi Poisson dapat terjadi karena banyaknya pengamatan yang memiliki nilai nol dalam variabel respon (excess zeros). Data yang mengalami overdispersi dan excess zeros dapat diselesaikan menggunakan regresi Hurdle Negative Binomial (HNB). Permasalahan yang terkait metode HNB dapat ditemukan dalam kasus kematian, di mana data yang digunakan berkaitan dengan jumlah kematian akibat filariasis di Jawa Timur pada tahun 2022. Hasil pengujian signifikansi parameter secara parsial dalam model regresi HNB menunjukkan bahwa persentase penduduk miskin, persentase sanitasi layak, persentase air bersih, jumlah sarana kesehatan, persentase indeks pembangunan manusia, persentase keluhan kesehatan berpengaruh secara signifikan terhadap jumlah kematian akibat filariasis.

Abstract

Seasonal Autoregressive Integrated Moving Average (SARIMA) adalah metode peramalan time series untuk model data fluktuatif dengan pola data musiman. Model Autoregressive Conditional Heteroskedastisitas (ARCH) adalah model yang berfungsi untuk mengatasi masalah heteroskedastisitas atau varians redisual dalam data time series. Salah satu implementasi dari model SARIMA ARCH yaitu untuk meramalkan jumlah produksi padi Kabupaten Ngawi. Data yang digunakan dalam penelitian ini adalah data bulanan pada bulan Januari 2019 sampai dengan Maret 2023. Hasil dari penelitian ini diperoleh model SARIMA (1,1,1)(0,1,2)(4) ARCH (8) dengan nilai RMSE sebesar 22.18279. Kata Kunci: Produksi Padi, Peramalan, SARIMA ARCH.

Abstract

This research gives more explaination in proof of theorem. The theorem is about existence and uniqueness a point is called fixed point in an extended b-metric space. Beside that, also we give example about extended b-metric space.

Abstract

G was a graph with a set of vertices and a set of edges Graph Labeling was a mapping or function that paired every part of the graph (vertices, edges, or both) with a positive integer. A total vertex labeling on the graph was a bijective mapping from to the set of integer numbers in such a way that there was a positive integer k that satisfied for every . The research findings indicated that for the antiprism graph , it had a magic constant of . for odd n where Keywords: Magic Constant Number, Antiprism Graph, Magic Vertex Total Labeling
