Abstract, Summary, or Creative Statement

In this study, we examine the relationship between drug consumption, demographics, personality traits, and behavioral traits. All basic assumptions were met for our dataset and removing a few values with impossible outliers was our only major change. There were some collinearity issues found but due to the importance of certain values, we didn't remove any variables. We started off with a model of N-score as the response and predictors of: Impulsive, SS, Age, Gender, Alcohol, Cannabis, age and alcohol interaction, and age and cannabis interaction. Through model selection, we removed the interaction terms and ran our multiple linear regression on the remaining model. We then examined MSE and MAE of which we found that this model is not an overfit. From the regression, we ended up with an F-statistic of 7.915 and a p-value < 2.2e-16. The low F-statistic suggests that the model has weak explanatory power and the low p-value tells us that the model is statistically significant. The presence of these conflicting values, tells us that we can't interpret a practically important measure of prediction using our model.
