Before running any regressions make sure to check for multicollinearity. How did you check for multicollinearity? If there is mu

Answer:

Multicollinearity

Step-by-step explanation:

  • In a linear regression model, we predict the dependent variable(y) with the help of independent variable(x_i).
  • Our aim is to minimize the residuals and make the best prediction.
  • Multicollinearity refers to the situation when there is correlation between the independent variables.
  • This could lead to wrong predictions and increase residuals
  • Multicollinearity can be checked with the help of VIF, variance inflation factor.
  • The industry accepted value of VIF is 5. A VIF greater than 5 means collinearity.
  • In order to treat multicollinearityy, we could plot scatter plot between different independent variables and remove one of the variable that is correlated.
  • Before running the linear regression model, we should make sure that there is no correlation between independent and dependent variable, residuals to be normally distributed, no auto correlation.

There are 8 numbers for the computer to choose from.
So the probability of choosing a particular number is 1/8.
The first number can be any one of the 8.
The second and the third must be the same as the first, with probability 1/8.

Therefore the probability that all three numbers are the same
= (1/8)(1/8) = 1/64   [ player will win a prize ]

Answer:

Correct answer is : $220

Step-by-step explanation:

Here, cost price = $66

Let the selling price be $x.

According to the statement given in problem,

Selling price - cost price = 70% of selling price

i.e.  x  - 66 = 70% * x

x - 70x/100 = 66

30x / 100 = 66

x = 6600 / 30 = $220

i.e Selling price = $220
