Now in its third edition, this highly successful text has been fully revised and updated with expanded sections on cutting-edge techniques including Poisson regression, negative binomial regression, multinomial logistic regression and proportional odds regression. As before, it focuses on easy-to-follow explanations of complicated multivariable techniques. It is the perfect introduction for all clinical researchers. It describes how to perform and interpret multivariable analysis, using plain language rather than complex derivations and mathematical formulae. It focuses on the nuts and bolts of performing research, and prepares the reader to set up, perform and interpret multivariable models. Numerous tables, graphs and tips help to demystify the process of performing multivariable analysis. The text is illustrated with many up-to-date examples from the medical literature on how to use multivariable analysis in clinical practice and in research.

Chemists across all subdisciplines use Excel to record data in tabular form, but few have learned to take full advantage of the program. Featuring clear step-by-step instructions, Excel for Chemists illustrates how to use the scientific calculating power of Excel to perform a variety of chemical calculations. Including a CD-ROM for Windows, this new edition provides chemists and students with a detailed guide to using the current versions of Excel (Excel 2007 and 2010) as well as Excel 2003. Additional features in this third edition include: How to perform a variety of chemical calculations by creating advanced spreadsheet formulas or by using Excel’s built-in tools; How to automate repetitive tasks by programming Excel’s Visual Basic for Applications; New chapters show how to import data from other language versions of Excel, and how to create automatic procedures; The accompanying CD contains a number of Excel macros to facilitate chemical calculations, including molecular weight, nonlinear regression statistics, and data interpolation; Several appendices provide extensive lists of useful shortcut keys and function descriptions.

This book is a compilation and discussion of the outstanding scientific research activities concerning actually and future applications of LAB. It is directed to a vast public of readers - researcher, academics, corporate RD, students or just curious interested in the subject.
