THE USE OF SEPARATE PREDICTION FORMULAE BASED ON THE PROCUREMENT SOURCE OF OFFICER FLIGHT STUDENTS.
Abstract
Separate multiple prediction formulae were computed on each of the six major procurement source subgroups of the entering officer flight students. This procedure for developing prediction formulae was compared with two other conditions: a pseudovariable condition, which treats each procurement source as a separate dichotomous variable, and the current condition which treats the entire officer group as a whole without taking procurement source into account. Two criteria were used for this comparison, namely, the crossvalidation coefficients of each condition, and the disciminatory power of the respective conditions as measured by the percentage of attritions placed in the lowest 10 per cent of the respective predictor scores. The separate formula condition was the most valid upon crossvalidation and was also found to have the best discrimination at the low end of the range; however, its superiority in the former case failed to reach statistical significance.
