NO.PZ2015121801000090 问题如下 With respeto return-generating mols, the slope term of the market mol is estimate of the asset’s: A.totrisk. B.systematic risk. C.nonsystematic risk. is correct.In the market mol, Ri =αi +βiRm +ei, the slope coefficient, βi, is estimate of the asset’s systematic or market risk. 什么是 return generating mol

NO.PZ2015121801000090 beta是非系统性风险吧？这个改如何记？
systematic risk. nonsystematic risk. B is correct. In the market mol, Ri =αi +βiRm +ei, the slope coefficient, βi, is estimate of the asset’s systematic or market risk.请问 slope应该是Rm吧？beta是横轴变量呀？
systematic risk. nonsystematic risk. B is correct. In the market mol, Ri =αi +βiRm +ei, the slope coefficient, βi, is estimate of the asset’s systematic or market risk.return generate mol是多因素模型，market mol是单因素模型，这两个人不是一回事儿吧？为什么出现在一道题目里？我有点迷惑
