Qualification: Using the Correct Statistical Test for the Equality of Regression Coefficients
The 0.0266 slope difference is an effect estimate. It is not, by itself, a test of whether the selection and random-survival trajectories differ. Paternoster, Brame, Mazerolle, and Piquero examine direct comparisons between regression slopes. They explain that the difference has its own sampling distribution and standard error. An incorrect standard-error estimator can bias the test toward rejecting equality. This supports Kaal's classification of the 0.0266 value as descriptive. A positive numerical difference may summarize the observed trajectories, but confirmatory inference requires uncertainty for the difference itself. The correspondence is limited. The external paper addresses independent samples in criminological regressions. Kaal's claim concerns an interim registered agent experiment. The public claim does not establish here whether the two slope estimates are independent, paired, or covariance-adjusted. The source neither recalculates the 0.0266 value nor validates the data, estimator, or selection mechanism. The value may describe this checkpoint. It cannot carry confirmatory weight without a comparison matched to the experimental dependence structure.
