A data scientist is working on a predictive modeling project with a target variable that follows a multinomial distribution because the target variable represents multiple unordered categories. Which procedure should they use to model this type of distribution while maintaining computational efficiency?

A data scientist is evaluating the performance of a neural network model for a regression problem. After training, the scientist wants to assess the model's ability to generalize to new data. Which of the following metrics is the most appropriate for evaluating the performance of the neural network on a validation dataset?

A data scientist is using the SAS system to preprocess data for predictive modeling. They need to convert a character variable named `char_date` in the format 'yyyy-mm-dd' to a SAS date variable. Which INPUT statement below correctly performs this conversion?

You are required to use PROC NEURAL in SAS to construct a neural network model that minimizes overfitting. Which combination of options would be most effective for this purpose?

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?
