Regression analysis is a statistical process which enables prediction of relationships between variables. The predictions are based on the casual effect of one variable upon another. Regression techniques for modeling and analyzing are employed on large set of data in order to reveal hidden relationship among the variables.This book will give you a rundown explaining what regression analysis is, explaining you the process from scratch. The first few chapters give an understanding of what the different types of learning are – supervised and unsupervised, how these learnings differ from each other. We then move to covering the supervised learning in details covering the various aspects of regression analysis. The outline of chapters are arranged in a way that gives a feel of all the steps covered in a data science process – loading the training dataset, handling missing values, EDA on the dataset, transformations and feature engineering, model building, assessing the model fitting and performance, and finally making predictions on unseen datasets. Each chapter starts with explaining the theoretical concepts and once the reader gets comfortable with the theory, we move to the practical examples to support the understanding. The practical examples are illustrated using R code including the different packages in R such as R Stats, Caret and so on. Each chapter is a mix of theory and practical examples.By the end of this book you will know all the concepts and pain-points related to regression analysis, and you will be able to implement your learning in your projects.

Najlepsza praca świata? Oczywiście rekruter w IT! Branża IT jest dość nietypowa. Poza nielicznymi wyjątkami ― jak specjaliści od sprzętu ― większość osób realizujących projekty informatyczne, tworzących oprogramowania i podtrzymujących działanie systemów może pracować zdalnie. Co więcej, zdalnie oznacza czasem operowanie z drugiego końca świata, w ramach międzynarodowych zespołów, których członkowie spotykają się via komunikatory i na zebraniach online. I wszystko to potrafi zadziwiająco sprawnie funkcjonować! Skoro firmy z branży informatycznej są tak bardzo "zdalne", może także pracownicy HR, może również rekruterzy byliby w stanie funkcjonować bez codziennego pojawiania się w biurze? Czytać maile na plaży na Bali, Zanzibarze czy choćby we Włoszech . Realizować powierzone sobie zadania w sposób uporządkowany i systematyczny o godzinie, która najbardziej im odpowiada. I zarabiać przy tym kwoty rzędu kilkudziesięciu tysięcy na miesiąc. Jeśli taka wizja pracy w roli rekrutera w IT do Ciebie przemawia i zastanawiasz się, jak zmienić tę wizję w rzeczywistość, to przestań marzyć, a zacznij czytać tę książkę. Jej autor konkretnie, krok po kroku pokaże Ci, co musisz zrobić, by dołączyć do światowej armii digital recruiter nomads i pracować, skąd chcesz, jak chcesz i w godzinach, które Ci odpowiadają.
