The exogenous administration of the brain/gut peptide cholecystokinin (CCK) inhibits food intake in a variety of species, including subhuman primates and humans. To determine the role of endogenously released CCK in the control of food intake in rhesus monkeys, we examined the ability of the selective type A and type B CCK antagonists devazepide and(More)
A role for the brain/gut peptide cholecystokinin (CCK) in the control of gastric emptying has been proposed. In the present studies, we have used a potent type A CCK-receptor antagonist (devazepide) to examine the quantitative contribution of endogenously released CCK in the control of liquid gastric emptying of 100 ml lipid, protein, and carbohydrate test(More)
Alpha is the amount by which the returns from a given asset exceed the returns from the wider market. The standard way of estimating alpha is to correct for correlation with the market by regressing the asset's returns against the market returns over an extended period of time and then apply the t‐test to the intercept. The difficulty is that the residuals(More)
1 A Martingale Test for Alpha Dean P. Foster, Robert Stine, and H. Peyton Young December 31, 2008 We present a new method for testing whether a fund manager’s track record allows us to infer that he is able to beat the market with high probability or is just plain lucky. The test is based on the martingale maximal inequality. Unlike other standard(More)
