Abstract

Poisson regression is one of model that is often used to model the relationship between response variables in the form of discrete data with a set of predictor variables in the form of continuous, discrete, category, or mixture data. In Poisson regression assumes that the mean of the response variable equal to the variance (equidispersion). But in reality, sometimes found a condition called overdispersion, that the variance value is greater than the mean. One of the cause of overdispersion is excess zero in the response variable. One of model that can be used to overcome this overdispersion problem is Zero-Inflated Poisson (ZIP) regression  model. This model is applied on a case study of motor vehicle insurance in the branch of PT. Asuransi Sinar Mas in Semarang in 2010 to determine the effect of age of car and types of coverage to number of claims filed by the policyholder to the branch of PT. Asuransi Sinar Mas in Semarang. In this case, the occurrence of zeros due to many policyholders did not file a claim to the branch of PT. Asuransi Sinar Mas in Semarang. From the analytical result obtained the conclution that the age of car and types of coverage affect number of claims filed by the policyholder to the branch of PT. Asuransi Sinar Mas in Semarang in 2010.   Keywords: Poisson Regression, Overdispersion, Zero-Inflated Poisson (ZIP) Regression

Abstract

Pemberian gizi yang tepat dapat mengurangi gejala Attention Deficit Hyperactivity Disorder (ADHD). Akan tetapi anak-anak mudah bosan bila diberikan makanan yang sama secara terusmenerus. Selain itu, harga makanan juga diperhatikan oleh orang tua. Dalam penelitian ini dicari solusi optimal dari permasalahan penyusunan menu makanan menggunakan algoritme genetika. Dalam penyelesaian masalah ini digunakan representasi integer permutasi dengan panjang kromosom 12 gen pada tiap harinya. Gen-gen tersebut merupakan representasi dari menu makanan yang terdiri dari karbohidrat, protein, dan lemak. Metode crossover yang digunakan adalah one-cut point, sedangkan untuk metode mutasi menggunakan exchange mutation. Pada tahap seleksi digunakan metode elitism selection. Dari hasil pengujian yang sudah dilakukan didapatkan parameter optimal yaitu menggunakan 50 generasi dengan nilai rata-rata fitness yang didapatkan 13.928. Hasil akhir yang didapat yaitu susunan menu makanan sesuai dengan jumlah hari yang diinginkan.

Abstract

Representation of a finite group G over generator linear non singular mxm matrix with entries of field K defined by group homomorphismA : G → GLm(K)Basically, the non singular mxm matrix A(x) which representing the finite group G divided into two, that are the unitary matrix and non unitary matrix . If A(x) is a non unitary matrix, then there exist a unitary matrix which similar to A(x). This research deals to analyze the numbers of one example of a unitary matrix representation over arbitrary finite group G with order n that is permutation matrix, and the number of unitary matrix which is similar to real non unitary matrix representation of arbitrary finite group G order 2. The results showed the numbers of permutation matrix representation is n! and unitary matrix which is similar to non unitary matrix representation is 2.
