问题如下：
With respect to return-generating models, the slope term of the market model is an estimate of the asset’s:
选项：
A. total risk.
B. systematic risk.
C. nonsystematic risk.
解释：
B is correct.
In the market model, Ri =αi +βiRm +ei, the slope coefficient, βi, is an estimate of the asset’s systematic or market risk.
return generate model是多因素模型，market model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

嗨，爱思考的PZer你好：
同学你好，原版书是这样表述的
A return-generating model is a model that can provide an estimate of the expected
return of a security given certain parameters. If systematic risk is the only relevant
parameter for return, then the return-generating model will estimate the expected
return for any asset given the level of systematic risk.
As with any model, the quality of estimates of expected return will depend on
the quality of input estimates and the accuracy of the model. Because it is difficult to
decide which factors are appropriate for generating returns, the most general form
of a return-generating model is a multi-factor model
简单来说，risk generating model并不一定是多因素模型，如果系统性风险时唯一影响因素，那么也是可以使用此模型的

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. 老师您好， multifactor模型反应的β也包含funmentfactors，而funmentfactors不就是反映了非系统性风险吗。那么为什么说beta只反应了系统性风险呢。
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？
return-generating mols是什么呀
