The differential effect of the two treatments is the effect of applying one treatment in lieu of the other. In randomised experiments, the differential effect is of no more or less interest than other treatment contrasts. Differential effects play a special role in certain observational studies in which treatments are not assigned...
Residual frequency effects compensation
A means is provided to estimate the amount of frequency deviation experienced in a precision resonator resulting from the effects of previous thermal history, acceleration, or aging by determining the differential effect of the perturbing condition on different resonant modes in the same resonator or on different resonators exposed to the same environment. The measurements may be made simultaneously, or sequentially against an independent frequency source. Residual frequency hysteresis effects may be determined in connection with an independent temperature sensor if the exact temperature in not known.
