"This is a clear treatment of how to carefully present results from model-fitting in a wide variety of settings. It is a boon to anyone who has to present the tangible meaning of a complex model in a clear fashion, regardless of the audience. As an example, many experienced researchers start to squirm when asked to give a simple explanation of the applied meaning of interactions in nonlinear models such as logistic regression. The tools in Mitchell's book make this task much more enjoyable and comprehensible"

"ABSTRAKSalah 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%.

ABSTRACTOne 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."

"Summary: This collection of articles from Stata Journal and Stata Technical Bulletin provide a detailed description of a range of meta-analytic methods. They show how to conduct and interpret meta-analysis; how to produce flexible graphical displays; how to use meta-regression; how to examine bias, and how to conduct multivariate mea-analysis."

"Untuk memodelkan data cacah atau count data, model regresi yang biasa digunakan adalah model regresi Poisson. Model regresi Poisson mengasumsikan mean pada variabel respon sama dengan variansinya atau dikenal dengan istilah equidispersion. Apabila regresi Poisson digunakan untuk kondisi selain equidispersion, yaitu overdispersion dan underdispersion, maka nilai standard error dari estimasi parameter model menjadi tidak konsisten. Salah satu alternatif model regresi untuk mengatasi overdispersion maupun underdispersion adalah model regresi double Poisson. Model regresi double Poisson mengasumsikan variabel respon berdistribusi double Poisson. Distribusi double Poisson diperoleh menggunakan definisi dari keluarga distribusi double eksponensial. Parameter pada model regresi double Poisson diestimasi menggunakan metode maksimum likelihood dan solusi dari persamaan log-likelihoodnya diselesaikan menggunakan metode numerik Newton-Raphson. Penerapan model regresi double Poisson pada data kepiting tapal kuda menunjukan bahwa hanya variabel weight yang berpengaruh signifikan terhadap banyak kepiting satelit yang berkerumun ke sarang kepiting tapal kuda betina. Selain itu, interpretasi dari model regresi double Poisson juga serupa dengan model regresi Poisson sebab keduanya menggunakan fungsi penghubung log.

To model count data, the most commonly used regression model is the Poisson regression model. The Poisson regression model assumes that the mean of the response variable is equal to the variance, also known as equidispersion. If Poisson regression is used for conditions other than equidispersion, namely overdispersion and underdispersion, then the standard error value of the estimated model parameters becomes inconsistent. One of the alternative regression models to overcome overdispersion and underdispersion is the double Poisson regression model. The double Poisson regression model assumes that the response variable has a double Poisson distribution. The double Poisson distribution is obtained using the definition of the double exponential distribution family. The parameters in the double Poisson regression model were estimated using the maximum likelihood method and the solutions of the log-likelihood equation were solved using the Newton-Raphson numerical method. The application of the double Poisson regression model to the horseshoe crab data shows that only the variable weight has a significant effect on the number of satellite crabs swarming to the nests of female horseshoe crabs. In addition, the interpretation of the double Poisson regression model is also similar to the Poisson regression model because both use a log link function."
