Tugas akhir ini membahas mengenai distribusi invers gaussian yang merupakan distribusi probabilitas kontinu yang dapat mengatasi masalah kemencengan dan long-tail. Pembahasan meliputi fungsi kepadatan probabilitas, fungsi distribusi, fungsi survival, fungsi hazard, serta membentuk fungsi pembangkit momen. Kemudian, dicari bentuk mode, mean, variansi, kemencengan, dan kurtosis distribusi invers gaussian. Terakhir, dicari taksiran parameter dan distribusi dari taksiran parameter menggunakan MLE. Data Jug Bridge mengenai drainase digunakan sebagai ilustrasi. ...... This paper discusses about Inverse Gaussian Distribution, the continued probability distribution which can solve skew and long tail problem. At first, we study about probability density function, cumulative distribution function, survival function, hazard function, and form moment generating function. Then, we seek mode, mean, variance, skewness, and kurtosis of inverse gaussian distribution. Finally, we try to discover parameter estimation and distribution of parameter estimation using MLE. Jugde Bridge data about drianage will be used as illustration.

The Birnbaum-Sanders (BS) distribution was first introduced in 1969 by Birnbaum and Saunders as a combination of inverse Gaussian distributions with a length-biased inverse Gaussian distribution. Later, in 2008, Ahmed et al. introduced a new parametrization of the BS distribution based on Birnbaum-Sanders, and they also proposed a parameter estimation using the method of moments and regression-quantile estimation. In this paper, we emphasize the Birnbaum-Sanders distribution presented by Ahmed et al., and we develop an EM-algorithm to estimate two unknown parameters of this distribution. The EM-algorithm is a general method used to estimate the parameters when the probability density function is complicated and it is the best alternative for the estimation of a mixture distribution. We assumed that this problem has a missing value, and maximized complete data log-likelihood function instead log-likelihood function because it is analytically easier. Moreover, some simulation experiments were conducted in order to examine the performance of the proposed parameter estimation, and it was observed that the performances were quite satisfactory. Specifically, the MSE, variance and bias tend to decrease as n increases.

Pemodelan jumlah klaim mengklaim salah satu topik paspor adalah praktik lapangan. masalah ini sering ditemukan dalam model ingthataatais persebaran. Poisson dributiontion yang digunakan dalam pemodelan sumber klaim tidak dapat digunakan sebagai fakta overproperti penyebaran.Oleh karena itu, distribusi yang distandarisasi di luar negeri dapat dimanfaatkan jumlah klaim yang mengklaim pengungkapan properti yang dibutuhkan. Dalam tulisan ini, analternatif menerima distribusi yang dihasilkan, yaitu Distribusi Umum Biomial Negatif-Negatif Distribusi adalah distribusi distribusi negatif negatif dan distribusi Membalik Gaussie dan distribusi metameterisasi pada parameter negatif Distribusi binomial yaitu p = exp (), di mana nilai variabel acak acak yang didistribusikan Inverse Gaussian. Distribusi eksternal ini adalah unimodal, hasa tebal thailand hasa positif menghasilkan kewajiban koefisien. Dalam tesis tingkat bawah, kemungkinan serangan dan komitmen faktorial dari distribusi NB-IG yang didistribusikan. Berarti, varians, skewness danurturtasthasic properties ofNB-IG distribusi disajikan dan parameter pengujian diperlakukan melalui survival maksimum maksimum metode estimasi. Kepenuhan distribusi NB-IG diilustrasikan oleh data nyata set.

One topic of passports is field practice. this problem is often found in modeling the data distribution. tion used in modeling claims sources cannot be used as a fact of overproperty distribution. Therefore, standardized distributions abroad can be used the number of claims claimed In this paper, accept the resulting distribution, namely General Negative-Negative Biomial Distribution, Distribution is negative negative distribution and Gaussie Reverse distribution and metameterization distribution on negative parameters, binomial distribution ie p = exp (), where the variable value Varies Published InverseGaussian. This external distribution is immunodal, Thailand has a positive potential to produce the coefficient obligation. In the lower-level thesis, attacks and factorial commitments from the distributed NB-IG distribution are published. Means, variants, skewness and strictness of the properties of NB-IG distribution are presented and test parameters are approved through maximum maximum survival estimation method. The fullness of the NB-IG distribution is illustrated by real data sets.

Analisis regresi digunakan untuk mengetahui hubungan antara satu variabel respon dan satu atau lebih variabel penjelas. Ketika variabel respon berupa data count yaitu data yang berupa bilangan bulat non-negatif, analisis regresi yang sering digunakan adalah analisis regresi Poisson. Pada regresi Poisson terdapat asumsi kesamaan nilai mean dengan nilai variansinya. Dalam data count sering didapati kondisi dimana nilai variansi lebih besar dari nilai meannya atau disebut overdispersi. Pada data yang overdispersi, regresi Poisson kurang tepat jika digunakan karena nilai standard error dari taksiran parameter yang dihasilkan akanunderestimate sehingga beresiko memberikan kesimpulan yang tidak tepat. Model regresi Poisson-Inverse Gaussian dapat digunakan pada data count yang overdispersi dan memiliki tail panjang. Penaksiran parameter model regresi Poisson-Inverse Gaussian menggunakan metode maksimum likelihood dan solusi dari fungsi log -likelihood-nya menggunakan pendekatan numerik yaitu Newton-Raphson. Uji kesesuaian model yang digunakan mencakup statistik pseudo R-Squared, uji rasio likelihood, dan Uji Wald. ......Regression analysis is used to investigate the relationship between one response variable and one or more regressor variables. If the response variable is count data, that has non negative integer value, the regression analysis that usually used is Poisson Regression. Poisson regression has an assumption that mean of response variable equal to its variance. On count data frequently found that the variance is greater than mean, or called overdispersion. On overdispersion case, poisson regression is inconvenient to used because it may underestimate the standard error of regression parameters and consequently it risk to give misleading inference. Poisson Inverse Gaussian regression model can be used on overdispersion and long tail count data. Parameter estimation of Poisson Inverse Gaussian Regression Model can be obtained through the maximum likelihood method and the solution of log likelihood function may be solved by using numerical method called Newton Raphson. Goodness of fit testing of this model includes pseudo R Squared, rasio likelihood test, and Wald test.
