obberies. <str<strong>on</strong>g>The</str<strong>on</strong>g> <strong>on</strong>ly crime <strong>on</strong> which the two groups did not differ statistically is forcible<br />
rape (a subset <str<strong>on</strong>g>of</str<strong>on</strong>g> all sexual <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses), but this is most likely due to the very small number<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g> events.<br />
Fewer than 1 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> each group were charged with rape, but the<br />
probability is still more than three times greater in the n<strong>on</strong>-low risk group (.39% vs.<br />
.12%, p ≤ .160).<br />
Does the model’s sensitivity change under different definiti<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> serious <str<strong>on</strong>g>of</str<strong>on</strong>g>fending?<br />
We c<strong>on</strong>ducted similar analyses with the low and n<strong>on</strong>-low risk groups using two<br />
alternative definiti<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g>fending severity, based <strong>on</strong> UCR Part I <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses and <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses<br />
deemed to be more likely to involve a victim or serious damage (i.e., involving a greater<br />
ec<strong>on</strong>omic cost). Of course, the Philadelphia model was not designed to predict such<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g>fenses, so the purpose <str<strong>on</strong>g>of</str<strong>on</strong>g> this questi<strong>on</strong> is not to validate the model, but rather to<br />
examine the types <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses committed by probati<strong>on</strong>ers deemed to be at low risk <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
serious harm, and whether they could be c<strong>on</strong>sidered serious under alternative definiti<strong>on</strong>s.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> results <str<strong>on</strong>g>of</str<strong>on</strong>g> these analyses are presented in the remaining parts <str<strong>on</strong>g>of</str<strong>on</strong>g> Table 3.3.<br />
As we would expect from the preceding analysis, the low and n<strong>on</strong>-low risk groups<br />
also differ substantially and significantly <strong>on</strong> these alternative measures <str<strong>on</strong>g>of</str<strong>on</strong>g> severity.<br />
However, our alternative definiti<strong>on</strong>s slightly inflate the proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> both groups that<br />
would be identified as ‘serious’ <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders. 9.1 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> low risk <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders had been<br />
charged post-risk assessment with a UCR Part I <str<strong>on</strong>g>of</str<strong>on</strong>g>fense, which include murder and rape,<br />
and also burglary and motor vehicle theft. <str<strong>on</strong>g>The</str<strong>on</strong>g> proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> n<strong>on</strong>-low risk <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders<br />
charged with a UCR Part I <str<strong>on</strong>g>of</str<strong>on</strong>g>fense is 15.7 per cent. Low risk <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders are 42 per cent<br />
