那你具体哪一步不会按,你先把这一步的公式告诉我。打字或者截图。

考试所有计算都是都过计算器按的,我们有专门讲解计算器使用方法的视频课程。你可以参考一下。

就是没找到这个的按法呀……

不好意思,上一个答案回复岔了,N是先计算天,然后除以365得到年,再乘以12,最后得到月。

我是想问这个是计算器按出来的吗?不知道怎么计算N

残差值较小的观测值是是和用于该模型建模的,把这样的观测值剔除了,那么新的模型的拟合度就下降了,拟合度下降的表现之一就是R平方的降低。

NO.PZ2017092702000006 问题如下 For a lump sum investment of ¥250,000 investea stateannurate of 3% compounily, the number of months neeto grow the sum to ¥1,000,000 is closest to: A.555. B.563. C.576. A is correct. The effective annurate (EAR) is calculatefollows: E= (1 + Perioc interest rate)m – 1   E= (1 + 0.03/365)365 – 1   EAR= (1.03045) – 1 = 0.030453 ≈ 3.0453%. Solving for N on a financicalculator results in (where FV is future value anPV is present value): (1 + 0,030453)N = FVN/PV = (¥1,000,000/¥250,000)So,N = 46.21 years, whimultiplie12 to convert to months results in 554.5, or ≈ 555 months. 这题我EAR已经算出来是3.045,带入计算器知四求一不知道为什么算出来是46.21.
