Relative biological effectiveness (RBE) computed using fluence model with reference to gamma rays (left) and with reference to the average of square error (RMSE).gamma rays and protons (right). Goodness of fit is measured by sum of the squared errors (SSE), correlation coefficients (R2 and adjusted R2) and root mean
