计算器error4

  1. CFA I
  2. Portfolio

NO.PZ2015121801000068

问题如下：

An analyst has made the following return projections for each of three possible outcomes with an equal likelihood of occurrence:

If the analyst constructs two-asset portfolios that are equally weighted, which pair of assets provides the least amount of risk reduction?

选项：

A.

Asset 1 and Asset 2.

B.

Asset 1 and Asset 3.

C.

Asset 2 and Asset 3.

解释：

A  is correct.

An equally weighted portfolio of Asset 1 and Asset 2 has the highest level of volatility of the three pairs. All three pairs have the same expected return; however, the portfolio of Asset 1 and Asset 2 provides the least amount of risk reduction.

[2nd][7]进入data模式，依次输入X01=12，Y01=12；X02=0，Y02=6；X03=6，Y03=0，按完之后[2nd][8]进入STAT模式，按⬇️键，显示error4

嗨，从没放弃的小努力你好：


试一下直接按“2nd+ENTER”，即调用“SET”功能。

正常按一下后，“1-V”就应该变成“LIN”（如果不是，就多按几次2nd+ENTER，直到出现LIN为止）。在“LIN”模式下输入计算器即可。
