请问return-generating models 就是market model?
NO.PZ2015121801000089问题如下 With respeto return-generating mols, the intercept term of the market mol is the asset’s estimateA.beta.B.alpha.C.variance.is correct.In the market mol, Ri =αi +βiRm +ei, the intercept, αi, anslope coefficient, βi, are estimateusing historicsecurity anmarket returns.这是什么公式,在哪里讲过

老师问下 为什么A是错的
请问老师,答案中的slope coefficient应该是Rm吧?为什么是beta呢?
