[7] Reconviction rates are standardised using a logistic regression model with the following predictors: Copas rate, number of previous convictions, number of previous offences and CJA. The Copas rate is a single measure which reflects the intensity and length of the offender's criminal career (expressed as log (number of sanction occasions / (10 + years between first and current sanction))).
