"Analisis regresi linier adalah suatu teknik dalam statistika untuk memodelkan dan menganalisis hubungan linier antara variabel respon dengan variabel regresor. Metode penaksiran parameter regresi yang umum digunakan adalah metode ordinary least square (OLS) yang menghasilkan taksiran yang dinamakan taksiran least square. Dalam analisis regresi linier berganda, masalah yang sering terjadi adalah multikolinieritas. Multikolinieritas membuat penaksiran dengan menggunakan metode OLS menghasilkan taksiran least square yang tidak stabil, sehingga pada skripsi ini akan dibahas metode lain untuk mengatasi permasalahan ini. Metode yang diperkenalkan untuk mengatasi multikolinieritas diantaranya adalah metode GRR yang menghasilkan taksiran generalized ridge. Taksiran ini merupakan taksiran yang bias. Metode ini masih memiliki kekurangan, yaitu bias yang dihasilkan tidak dijamin akan selalu bernilai kecil. Untuk itu, Singh, Chaubey, dan Dwivedi (1986) memperkenalkan metode Jackknife Ridge Regression (JRR) yang menghasilkan taksiran Jackknife Ridge Regression. Taksiran ini akan mereduksi bias yang dihasilkan oleh taksiran generalized ridge sehingga terkait dengan data yang digunakan, nilai mean square error taksiran ini lebih kecil dibanding taksiran generalized ridge maupun taksiran least square.

Regression linear analysis is a statistical technique for modeling and investigating the linear relationship between the response variable and regressor variable. Ordinary least square (OLS) method is commonly used to estimate parameters and yields an estimator named least square estimator. Most frequently occurring problem in multiple linear regression analysis is the presence of multicollinearity. Estimation using OLS method in multicolinearity caused an unstable least square estimator, therefore this undergraduate thesis will explain other method which can solve this problem such as GRR method that yields a bias estimator, named generalized ridge estimator. Unfortunately, this method still has a shortcoming because the bias in resulting estimator is not always guaranteed to be small. To solve this problems, Singh, Chaubey, and Dwivedi (1986) introduced Jackknife Ridge Regression (JRR) method that yields Jackknife Ridge Regression estimator. This estimator will reduce the bias of generalized ridge estimator, thus related to the data used, the resulting mean square error value of this estimator is smaller than the two methods.

Bronson, Richard
"In this appealing and well-written text, Richard Bronson starts with the concrete and computational, and leads the reader to a choice of major applications. The first three chapters address the basics: matrices, vector spaces, and linear transformations. The next three cover eigenvalues, Euclidean inner products, and Jordan canonical forms, offering possibilities that can be tailored to the instructor's taste and to the length of the course. Bronson's approach to computation is modern and algorithmic, and his theory is clean and straightforward. Throughout, the views of the theory presented are broad and balanced and key material is highlighted in the text and summarized at the end of each chapter. The book also includes ample exercises with answers and hints."

"ABSTRAK
Salah satu langkah untuk mengatasi masalah malware yang sedang berkembang adalah dengan cara memprediksi tren serangan yang akan terjadi. Untuk menghasilkan prediksi yang tepat maka dibutuhkan sebuah data yang valid dan dalam jangka waktu yang cukup panjang. Setelah mendapatkan data time series kemudian akan diolah menggunakan persamaan regresi linear sehingga bisa dilihat hubungan antar variabel di periode yang akan datang. Serangan kepada jaringan internet Indonesia sepanjang tahun 2015 terkelompok menjadi 11 bagian dengan total jumlah serangan sebesar 3.162.943 yang berasal baik dari dalam negeri dan luar negeri. Dari hasil analisis diprediksi serangan jenis SQL dan Botnet Torpig akan terus berkembang hingga awal tahun 2016 dengan analisa kesalahan sebesar 5,14%.

ABSTRACT
One of action to overcome the malware problem is predicting the trend that will happen in the next period. In order to produce an accurate prediction, a valid data and in long term format is needed. After getting the time series data we will process that data using linear regression equation so that the relationship between variables and the prediction for the next period can be seen. Attack on Indonesia internet network throughout 2015 are grouped into 11 section with a total 3.162.943 number of attack who comes from both domestic and overseas. SQL and Botnet Torpig attack is predicted will continue to grow until early 2016 with 5.14% percentage error."

Davis, Timothy A.
"Computational scientists often encounter problems requiring the solution of sparse systems of linear equations. Attacking these problems efficiently requires an in-depth knowledge of the underlying theory, algorithms, and data structures found in sparse matrix software libraries. Here, Davis presents the fundamentals of sparse matrix algorithms to provide the requisite background. The book includes CSparse, a concise downloadable sparse matrix package that illustrates the algorithms and theorems presented in the book and equips readers with the tools necessary to understand larger and more complex software packages.
With a strong emphasis on MATLAB and the C programming language, Direct Methods for Sparse Linear Systems equips readers with the working knowledge required to use sparse solver packages and write code to interface applications to those packages. The book also explains how MATLAB performs its sparse matrix computations."

Meyer, Carl D.
"Matrix Analysis and Applied Linear Algebra is an honest math text that circumvents the traditional definition-theorem-proof format that has bored students in the past. Meyer uses a fresh approach to introduce a variety of problems and examples ranging from the elementary to the challenging and from simple applications to discovery problems. The focus on applications is a big difference between this book and others. Meyer's book is more rigorous and goes into more depth than some. He includes some of the more contemporary topics of applied linear algebra which are not normally found in undergraduate textbooks. Modern concepts and notation are used to introduce the various aspects of linear equations, leading readers easily to numerical computations and applications. The theoretical developments are always accompanied with examples, which are worked out in detail. Each section ends with a large number of carefully chosen exercises from which the students can gain further insight."
