Question: What does multicollinearity in linear regression refer to?

Options:

  1. High correlation between the dependent variable and independent variables
  2. High correlation among independent variables
  3. Low variance in the dependent variable
  4. Independence of errors

Correct Answer: High correlation among independent variables

Solution: 

Multicollinearity occurs when two or more independent variables in a regression model are highly correlated, which can affect the stability of coefficient estimates.

Questions & Step-by-Step Solutions

What does multicollinearity in linear regression refer to?
  • Step 1: Understand that in linear regression, we use independent variables to predict a dependent variable.
  • Step 2: Recognize that independent variables are the factors we think influence the outcome.
  • Step 3: Know that multicollinearity happens when two or more of these independent variables are very similar or related to each other.
  • Step 4: Realize that when independent variables are highly correlated, it can make it hard to determine their individual effects on the dependent variable.
  • Step 5: Understand that this can lead to unstable estimates of the coefficients, meaning the results can change a lot with small changes in the data.
  • Multicollinearity – Multicollinearity refers to the situation in linear regression where two or more independent variables are highly correlated, leading to unreliable coefficient estimates.
