What best describes the limit of rows for a predictive model in Salesforce?

The limit of rows for a predictive model in Salesforce is best described by the specific threshold that Salesforce documentation outlines for data preparation and model training. In this context, 400 rows is the maximum number of rows that can be utilized in creating a predictive model. This limitation ensures that the model is both effective and manageable.

The underlying reason for this limit is likely tied to the complexity of building a statistical model. With too many rows, the model may require more computational resources and time, leading to potential performance issues. Conversely, too few rows can result in an underfitted model that fails to generalize well to unseen data. The 400-row limit represents a balanced point that allows for adequate training of the model while maintaining efficiency in processing the data.

Understanding this limit is crucial for practitioners using Salesforce for analytics, as it directly impacts how data can be prepared and processed for building predictive solutions.
