问题如下:

Based on the output for Logistic Regression 1 in the table below, which of the following alternatives is closest to the probability that any ETF will be a winning fund?

选项:

A.

6.75%

B.

5.96%

C.5.67%

解释:

C is correct. We calculate the probability that an that an ETF will be a winning fund by using the variable estimates and the average values of the independent variables.

Using the equation for the probability, where we have seven independent variables,


Using the mean values and coefficient estimates of the independent variables, the probability of the average ETF being a winner is


P=0.05666=5.67%

This implies that for an ETF with the average values of the independent variables, there is a 5.67% probability that it will be a winning ETF.

嗨,努力学习的PZer你好:


计算Y值不需要考虑假设检验的结果,除非题干有明确说明,否则不需要去掉不显著的变量。
