Question
Refer to the exhibit. After analyzing a dataset, you report findings to your team: 1. Variables A and C are significantly and positively impacting the dependent variable. 2. Variable B is significantly and negatively impacting the dependent variable. 3. Variable D is not significantly impacting the dependent variable. After seeing your findings, the majority of your team agreed that variable B should be positively impacting the dependent variable. What is a possible reason the coefficient for variable B was negative and not positive?
Options
- AVariable B is interacting with another variable due to correlated inputs
- BVariable B needs a quadratic transformation due to its relationship to the dependent variable
- CThe information gain from variable B is already provided by another variable
- DVariable B needs a logarithmic transformation due to its relationship to the dependent variable
