An indirect effect requires an effect compartment with rates of appearance and disappearance.
There are far too many apps that require a "network effect" to function properly.
In fact, Kepler-62f may require a greenhouse effect to keep its ocean from freezing over, researchers said.
Finally, we are estimating a magnitude of change, rather than a rate of change, which would require a different effect size metric [48].
Additionally there was concern that the use of larval therapy may require a larger effect size in time to healing than originally proposed by the investigators.
Crossover trials also require a transient treatment effect to minimize carryover effects into the subsequent treatment periods.
Consequently, our results require an assumption of constant effect within integer categories.
Fifth, our analysis focused on single outcomes, requiring a large effect on a single outcome.
To be cost-effective a higher price for the drug requires a greater effect on HF incidence or mortality.
Studying these effects would require an individual-based model in order to incorporate many circulating serotypes.
This requires a release effect lasting over several months, ensuring the delivery of mineral nutrients as needed by the plants.
