This writing aims to analyze model black-scholes in the determination of the value of inexact from the price of an option type europe as well as simulasinya. The data used is information call option and put option for closing as well as the closing price ( price ) shares barnes group inc. The first thing is done by searching volatility stock prices to call option and put option. Based on the result analysis inexact terhadap the ordinal value from the price of call option and put option to use the model of black-scholes obtained the price of fair to call option is as much as $ 3.4940, on the circumstances of this the seller and buyer call option for achieving the break-even point. To put or libya option is as much as $ 0.0329, on the circumstances of it ' s called out of the money where a put option zero-sum and will not be executed. Next simulation model black-scholes in the determination of the value of inexact from the price call option and put option. The results of the simulation concluded that the longer time left to maturity hence the higher the price of an option.

Structural Equation Modeling ( SEM ) is a multivariate analysis were used to analyze the relationship between variables in a complex manner. University libraries in higher education has a vital role. University libraries can be said to be at the heart of higher education, as it became a major contributory factor for the implementation of Tri Dharma Perguruan Tinggi. Quality of service at the library is very important to the success of service is realized as a library service. This study aims to determine the SEM parameter estimation using Maximum Likelihood as well as to analyze the effect of variable quality and relationship marketing in relation to satisfaction, trust and loyalty student UIN Alauddin Makassar students. This study was conducted by questionnaire, the data obtained by distributing questionnaires to 116 respondents. The population in this study was student UIN Alauddin Makassar.

Multiple linear regression said to be good if it statistic theassumptions such as: normality assumption, heteroskedastisity, an errordoes not undergo autocorrelation and not occour multicolinearity. On theassumption that problem often arise in the multiple linear regressionassumptions are not fulfilled multicolinearity. Multicollinearity is acondition in which the data of the observations of the independent variablesoccuror have a relationship that is likely to be high. This study aimed tocompare the appropriate method to over come multicollinearity betweenridge regression and principal component analysis. Comparison criteriaused both methods, the mean square error (MSE) and the coefficient ofdetermination (R2), from the data is the simulation with Microsoft Excelthen the analysis was performed, in order to obtain the data first using ridgeregression has a value of MSE of 0.02405 and R2 of 82.4%, while theprincipal component analysis MSE value of 14.14 and R2of 37.5% while thedata second using ridge regression MSE has a value of 0.00216 and R2 of96.9%, while the principal component analysis MSE values of 5.15 and R2 of69.5%. From these results it can be concluded that ridge regression methodis better used.

Kematian neonatus adalah kematian bayi yang lahir hidup sampai dengan 28 hari sejak lahir. Angka kematian neonatal di Provinsi Sulawesi Selatan pada tahun 2018 masih cukup tinggi yaitu sebanyak 799 kasus. Oleh karena itu, diperlukan suatu analisis untuk mengetahui faktor-faktor apa saja yang berpengaruh signifikan terhadap jumlah kematian neonatus. Dalam penelitian ini, jumlah kematian neonatus dapat dimodelkan dengan menggunakan analisis regresi Poisson. Namun pada model ini terdapat masalah overdispersi sehingga analisis dilanjutkan dengan menggunakan analisis regresi Gaussian inverse Poisson sehingga diperoleh hasil hanya satu variabel yang berpengaruh signifikan terhadap jumlah kematian neonatus yaitu variabel persalinan ditolong oleh tenaga kesehatan (x〗_7)). Model regresi Gaussian inverse Poisson yang diperoleh untuk jumlah kematian neonatus di Provinsi Sulawesi Selatan tahun 2018 adalah μ̂=exp(4,97785−0,11603x7).
