Tom Swift, who began his career with factor analysis (1967), is pleased to announce that the "1973 Tom Swift Award for Data Abuse" has been won by LeRoy Stone and James Brosseau. They originally (Stone, et al., 1973) used 115 variables in a stepwise regression analysis to explain differences among 19 observations. They then claimed (Stone & Brosseau, 1973) to have tested the predictive validity of this model. This was done by regressing the 14 variables from the model on data from 18 new subjects. This "cross-validation" yielded a final model with six variables and an R2 of 0.76.
