After Stage 1 training, she accurately constructed 10 of 12 formulas matching the novel array of data points; however, when she was exposed to a set of curvefitting reciprocal functions during Baseline 2, she was unable to input any formulas matching these functions.
The relationships among the reciprocal functions of the estimates are
The reciprocal functions also bear the same relationships to R([beta]) as do the estimates
In considering biases for the reciprocal functions, it should be noted that ER(z) and the variance of R(z) do not exist because can be zero.
