1//! Trait extensions for ndarray and other types
2//!
3//! This module provides trait extensions that add useful methods to existing types,
4//! particularly for statistical operations and data manipulation that complement
5//! the core ndarray functionality.

8pub use crate::utils::scaling::StatsExt;

10// Additional trait extensions can be added here in the future
11// For example: Extensions for DataFrame operations, specialized array operations, etc.
