I am very new to Scilab and I have been having some problems. I have two columns of data, one column represents the data for the independent data (x) and the other represents the dependent data (y). Through Scilab, I need to find the (1) covariance of the parameters, (2) the uncertainty in the coefficients as well as drawing (3) a 95% confidence bound for the fitted regression line. However, I do not even know where to start. I would really appreciate if anyone could help me - it is really stressing me out
