Included in Oracle 11g Database is a compelling array of statistical functions. These include descriptive statistics, hypothesis testing, correlations analysis, test for distribution fit, cross tabs with Chi-square statistics, analysis of variance (ANOVA), and Pareto analysis. Oracle continues to expand its set of statistical functions for use far beyond basic querying. In addition to embedded statistical functions, Oracle Data Mining and Oracle OLAP (both Options to the Database) make the database a sophisticated, scalable and secure analytical engine.
