By popular request, today we added a full set of regression tools to FastFig. The general regression function, reg, can be used to perform single and multivariate least squared regressions using any function as a model. For the common single variate cases, we have provided five additional functions linear_reg, poly_reg, log_reg, pow_reg and exp_reg. All of these functions will return the values of the parameter variables, r2, the standard error and the total, regression and residual sum of squares for the regression. Enjoy!
