Collinearity - Study guides, Class notes & Summaries

it shows how you can detect if there is a multicollinearity in your observation.

This document provides a detailed explanation of the several rules of detecting the problem of Multicollinearity.

If the chance that any one of five telephone lines is busy at any instant is 0.01, then what is the probability that all the lines are busy? A. (0.01)^4 B. (0.01)^5 C. (0.01)^6 D. (0.01)^10 - ANSWER B. (0.01)^5 N = 5, p = 0.01, x = 5 Apply Standard formula for Binomial Distribution. Thus, option b is the correct answer. Who should complete the control phase after the successful completion and implementation of the first four phases of DMAIC? A. The green belt alone; the proj...

It includes multicollinearity its reasons and deductions and remedial measures of multicollinearity

Most common problems in fitting linear regression - 1. Non-linearity of the responsepredictor relationships 2. Correlation of error terms 3. Non-Constant variance of error terms 4. Outliers 5. High-leverage points 6. Collinearity How to check for linearity - 1. Check the scatterplot of Y vs. X variable. Is it linear? 2. OR residual plot vs. fitted plot (especially useful in multiple regression). We want to see no patterns in this plot

A microeconomist wants to determine how corporate sales are influenced by capital and wage spending by companies. She proceeds to randomly select 26 large corporations and record information in millions of dollars. A statistical analyst discovers that capital spending by corporations has a significant inverse relationship with wage spending. What should the microeconomist who developed this multiple regression model be particularly concerned with? - Collinearity The Variance Inflationa...
