老师您好, 我想问一下这道题为什么variance of error 是4.4%呢? 从题中的表格我认为ER(U.S. real estate equities)=0.6 E(global equity)+0.15 E(global bonds)+4.4%. error 给expected return的贡献是4.4%, 为什么答案中写的variance of errors is 4.4%呢?谢谢
其实是拒绝原假设的最小的显著性水平,但是检验统计量,却会有很多个呀,我们可以多做几次试验,有好几个检验统计量,对应的P值也会有好多个,哪一个是最小的呢???怎么理解讲义中的这个最小呢?毕竟一次实验得到的统计量所对应的P值,未必是最小的呀。
请问老师这道题在2022年是不是不能这样考了?2022原版书L1V3的458页和讲义不一样了: 1 The lease transfers ownership of the underlying asset to the lessee. 2 The lessee has an option to purchase the underlying asset and is reasonably certain it will do so. 3 The lease term is for a major part of the asset’s useful life. 4 The present value of the sum of the lease payments equals or exceeds substantially all of the fair value of the asset. 5 The underlying asset has no alternative use to the lessor.
查看试题 已回答请问货币主义理论的依据是货币数量论吗?货币数量论是基于货币中性理论建立的,而货币中性理论说货币的供给不会影响gdp等real variable,而货币主义理论说经济周期的产生原因是政府无规律的乱发货币引起的,两者是冲突的吧?
