A TypeScript library providing advanced quantitative finance functions for risk analysis, performance metrics, and technical indicators. (Currently in development)

/**
 * Finds the minimum and maximum values in a specified column across all lists in a dictionary.
 *
 * @template T - The type of objects contained in the lists.
 * @template K - The key of the column to find extremes for.
 * @param dict - A dictionary where each key maps to an array of objects of type T.
 * @param columnName - The key of the column to evaluate for extremes.
 * @returns An object containing the minimum (`min`) and maximum (`max`) values found in the specified column,
 *          or `undefined` if no values are present.
