A standard statistical method used in regression analysis to estimate the unknown parameters in a linear regression model by minimizing the sum of the squares of the differences between the observed and predicted values. In crypto, OLS can be applied to model relationships between digital asset prices, trading volumes, and various on-chain metrics.
Mechanism
OLS operates by finding the line of best fit through a set of data points, where the sum of the squared residuals (the vertical distances from data points to the regression line) is minimized. For crypto market analysis, this involves specifying a dependent variable, such as a token’s price, and independent variables, which might include network activity, sentiment indicators, or macro-economic factors, to quantify their influence.
Methodology
Applying OLS requires careful consideration of assumptions, including linearity, homoscedasticity, and independence of errors. In crypto trading strategies and risk modeling, OLS provides a foundational approach for predicting price movements, identifying correlations between assets, or assessing the impact of specific events, though its linear assumptions may require augmentation with non-linear models for optimal predictive power in volatile digital asset markets.
