Quantitative Methods in Criminology [PDF ebook] 

This informative reference volume features the key papers in the growing field of quantitative criminology. The papers provide examples of the importation of statistical methods from other fields to criminology, the adaptation of such methods to special criminological problems through introspection, and the development of new innovative statistical approaches. The volume illustrates the growing sophistication and maturation of quantitative methods in this field. Divided into five parts: research design, sampling, issues in measurement, descriptive analysis and causal analysis, it will be of interest to anyone concerned with criminology and criminal justice, as well as those with specialized interests in quantitative methods.
