Significance levels: *significant at 10%; **significant at 5%; ***significant at 1%. (1) OLS with fixed effects; (2) FGLS with AR1 correction; and (3) 2SLS using as instruments the past values of the endogenous policy variables: training, policy cluster and continuity in implementation.
In the appetitive training endogenous OA would mediate the positive reinforcement participating in the formation of the context-food memory.
However, as training is endogenous, we have to control for selection bias both on observables and on unobservables.
To deal with endogenous selection into the training program, we use a regression discontinuity design, exploiting the fact that a fixed number of applicants are taken into the training program based on a pre-training score.
WISER Sister was a randomized controlled trial which examined effects of two doses of exercise training on endogenous sex hormone exposure, hormonally active breast tissue, and other breast cancer risk factors.
To test whether the better learning performance that we observed at ZT3 relies on an endogenous circadian rhythm, we trained bees that were kept in DD.
We use an unsupervised Chinese word segmentation system and binomial test to extract specific and endogenous lexicon chunks from the training corpus.
We aimed to identify endogenous metabolites that distinguish the trained from the untrained state to increase the spectrum of analytes amenable for hypothesis testing and to expand understanding of putative beneficial pathways.
Aerobic training interventions can enhance endogenous antioxidant activity in human and animal models[36], [37], although not all studies on this have shown consistent findings[38].
Nevertheless, the study is limited because of its cross-sectional nature; provider characteristics, the sector in which they work, and training level may be endogenous variables.
