Racketeering is an additional charge that prosecutors can bring for a pattern of crimes committed through an illegal enterprise.
adjusted r2is equivalent to r2. However, at small values of n that are used in pharmacokinetic analysis (e.g. <10), the adjusted r2can be significantly different from r2. For example, moving from 4 data points to 5 data points, the adjusted r2statistic is multiplied by 0.75, or given...
