  • Question 1
    • When preparing data for a predictive modeling project, a data scientist notices that the categorical variable 'payment_type' with four categories ('credit card', 'debit card', 'paypal', 'other') exhibits a high degree of variability in the outcome variable (purchase amount). To improve the model's predictive accuracy, what strategy can the data scientist use to handle the 'payment_type' variable?



      Answer: B
  • Question 2
    • When integrating SAS and R to perform advanced predictive modeling, it's crucial to correctly set up the SAS environment to communicate with R. Assuming that the R software is properly installed on the same machine as SAS, which of the following steps is essential to allow SAS to properly connect to and execute R scripts?



      Answer: A
  • Question 3
    • Which of the following link functions is appropriate when using the HP GLM node for a binary outcome variable in a logistic regression model?



      Answer: C
  • Question 4
    • You are analyzing a dataset with a linear regression model to predict sales revenue based on multiple input variables. To prevent overfitting, you decide to include a penalty for including too many variables in the model. Which property adjustment are you most likely to use?

      Answer: B
  • Question 5
    • You have a decision tree with a depth of 4. During validation, you observe the following characteristics: Leaf nodes at the lower depths have higher confidence for the predicted class but represent a smaller portion of the dataset. Conversely, upper-level nodes cover more of the dataset but with lower confidence levels. Given this scenario, which of the following strategies might help in improving the model’s performance without overfitting?
