Maximum Likelihood Estimation with Stata Fifth Edition

Maximum Likelihood Estimation with Stata Fifth Edition

Maximum Likelihood Estimation with Stata Fifth Edition is the essential reference and guide for researchers in all disciplines who wish to write maximum likelihood (ML) estimators in Stata. Beyond providing comprehensive coverage of Stata’s commands for writing ML estimators the book presents an overview of the underpinnings of maximum likelihood and how to think about ML estimation. The fifth edition includes a new second chapter that demonstrates the easy-to-use mlexp command. This command allows you to directly specify a likelihood function and perform estimation without any programming. The core of the book focuses on Stata's ml command. It shows you how to take full advantage of ml’s noteworthy features: Linear constraints Four optimization algorithms (Newton–Raphson DFP BFGS and BHHH) Observed information matrix (OIM) variance estimator Outer product of gradients (OPG) variance estimator Huber/White/sandwich robust variance estimator Cluster–robust variance estimator Complete and automatic support for survey data analysis Direct support of evaluator functions written in Mata When appropriate options are used many of these features are provided automatically by ml and require no special programming or intervention by the researcher writing the estimator. In later chapters you will learn how to take advantage of Mata Stata's matrix programming language. For ease of programming and potential speed improvements you can write your likelihood-evaluator program in Mata and continue to use ml to control the maximization process. A new chapter in the fifth edition shows how you can use the moptimize() suite of Mata functions if you want to implement your maximum likelihood estimator entirely within Mata. In the final chapter the authors illustrate the major steps required to get from log-likelihood function to fully operational estimation command. This is done using several different models: logit and probit linear regression Weibull regression the Cox proportional hazards model random-effects regression and seemingly unrelated regression. This edition adds a new example of a bivariate Poisson model a model that is not available otherwise in Stata. The authors provide extensive advice for developing your own estimation commands. With a little care and the help of this book users will be able to write their own estimation commands-commands that look and behave just like the official estimation commands in Stata. Whether you want to fit a special ML estimator for your own research or wish to write a general-purpose ML estimator for others to use you need this book.

A Gentle Introduction to Stata Revised Sixth Edition

A Gentle Introduction to Stata Revised Sixth Edition

Alan C. Acock's A Gentle Introduction to Stata Revised Sixth Edition is aimed at new Stata users who want to become proficient in Stata. After reading this introductory text new users will be able to not only use Stata well but also 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 part 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. 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 explaining 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 multilevel modeling in a very approachable manner. Acock teaches Stata commands by using the menus and dialog boxes while still stressing the value of Stata commands and 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 naturally. Real datasets such as the General Social Surveys from 2002 2006 and 2016 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 revised sixth edition is fully up to date for Stata 17 including updated discussion and images of Stata's interface and modern command syntax. In addition examples include new features such as the table command and collect suite for creating and exporting customized tables as well as the option for creating graphs with transparency.
