Correlation — อภิธานศัพท์

A measure of the linear relationship between two variables, ranging from -1 (inverse) to +1 (direct).

รายละเอียดทางเทคนิค

Correlation is applied in computing through numerical algorithms that balance precision, performance, and memory. JavaScript uses 64-bit IEEE 754 floating-point for all numbers, providing ~15-17 significant decimal digits. For exact arithmetic (financial, cryptographic), BigInt or fixed-point libraries are required. Browser-based calculators implement correlation using the same floating-point engine, making awareness of precision limitations important for correct results.
