    1. Beskrivelse

      Alan C. Acock's A Gentle Introduction to Stata, Fifth Edition,

      is aimed at new Stata users who want to become proficient in Stata.

      After reading this introductory text, new users will be able not only

      to use Stata well but also to learn new aspects of Stata.

      Acock assumes that the user is not familiar with any statistical

      software. This assumption of a blank slate is central to the structure

      and contents of the book. Acock starts with the basics; for example,

      the portion of the book that deals with data management begins with a

      careful and detailed example of turning survey data on paper into a

      Stata-ready dataset on the computer. When explaining how to go about

      basic exploratory statistical procedures, Acock includes notes that

      will help the reader develop good work habits. This mixture of

      explaining good Stata habits and good statistical habits continues

      throughout the book.

      Acock is quite careful to teach the reader all aspects of using Stata.

      He covers data management, good work habits (including the use of

      basic do-files), basic exploratory statistics (including graphical

      displays), and analyses using the standard array of basic statistical

      tools (correlation, linear and logistic regression, and parametric and

      nonparametric tests of location and dispersion). He also successfully

      introduces some more advanced topics such as multiple imputation and

      structural equation modeling in a very approachable manner. Acock

      teaches Stata commands by using the menus and dialog boxes while still

      stressing the value of do-files. In this way, he ensures that all

      types of users can build good work habits. Each chapter has exercises

      that the motivated reader can use to reinforce the material.

      The tone of the book is friendly and conversational without ever being

      glib or condescending. Important asides and notes about terminology

      are set off in boxes, which makes the text easy to read without any

      convoluted twists or forward-referencing. Rather than splitting topics

      by their Stata implementation, Acock arranges the topics as they would

      appear in a basic statistics textbook; graphics and postestimation are

      woven into the material in a natural fashion. Real datasets, such as

      the General Social Surveys from 2002 and 2006, are used

      throughout the book.

      The focus of the book is especially helpful for those in the

      behavioral and social sciences because the presentation of basic

      statistical modeling is supplemented with discussions of effect sizes

      and standardized coefficients. Various selection criteria, such as

      semipartial correlations, are discussed for model selection. Acock

      also covers a variety of commands available for evaluating reliability

      and validity of measurements.

      The fifth edition of the book includes two new chapters that cover

      multilevel modeling and item response theory (IRT) models. The

      multilevel modeling chapter demonstrates how to fit linear multilevel

      models using the mixed command. Acock discusses models with

      both random intercepts and random coefficients, and he provides a

      variety of examples that apply these models to longitudinal data. The

      IRT chapter introduces the use of IRT models for evaluating a set of

      items designed to measure a specific trait such as an attitude, value,

      or a belief. Acock shows how to use the irt suite of commands,

      which are new in Stata 14, to fit IRT models and to graph the results.

      In addition, he presents a measure of reliability that can be computed

      when using IRT.
