Risk-adjusted return ratios in python Let us now find out the various measures along with the formula of each for risk-adjusted return in Python. The following are the measures: Sharpe ratio Information ratio Modigliani ratio (M2 ratio) Treynor Ratio Jensen’s Alpha R-squared Sortino Ratio...
回归平方和占总平方的比例,用R^2表示,其值在0到1之间。 R^2 == 0:说明y的变化与x无关,x完全无助于解释y的变差 R^2 == 1:说明残差平方和为0,拟合是完全的,y的变化只与x有关(理想情况下) 显著性检验 显著性检验的主要目的是根据所建立的估计方程用自变量x来估计或预测因变量y的取值。当建立了估计...
In the code above, we are calculating R-squared value using the formula:1 - (sum of squared residuals / sum of squared total variation). The squared residuals are obtained by subtracting the predicted values (yhat) from the observed values (y), then we square the differences, and sum them...
