$Royston P., Sauerbrei W. Multivariable model-building: a pragmatic approach to regression analysis based on fractional polynomials for continuous variables$

Chichester, JohnWiley & Sons Ltd, 2008. - 324p.

Работа посвящена построению математических моделей (на примере медицинских и биологических задач) при помощи регрессионного анализа с использованием полиномов дробных степеней (ограничиваясь набором -2; -1; -0.5; 0; 0.5; 1; 2, причём под "степенью 0" понимается логарифмическое преобразование). Рассматриваются вопросы выбора подмножества переменных, включения в рассмотрение, наряду с количественно измеримыми, также "качественных" (номинальных или порядковых) переменных, процедуры построения модели, включая выбор дробных степеней, для одномерного и многомерного случаев, проверка статистической значимости модели и её устойчивости, проводится сравнение таких моделей с другими, направленными на ту же задачу (сплайновыми, логит- и пробит-регрессией и т.п.), даются практические рекомендации.
Для специалистов по статистической обработке данных и использующих статистическую обработку в исследованиях, а также аспирантов и студентов соответствующих специальностей.

2004, John Wiley & Sons, Inc; 558 pages. Regression models, in some form or another, are ubiquitous in social data analysis. Although classic linear regression assumes a continuous dependent variable, later incarnations of the technique allowed the response to take on a variety of more limited forms: binary, multinomial, truncated, censored, strictly integer, and others. Increasingly, regression texts are incorporating some limited-depende...
