Hello I have some data points which have errors on both x and y coordinates. I want to fit a straight line to them but I am not sure how to take the error on x into account. Normally, when I have just the error on y, I want to minimize $$\sum\frac{(y_{pred}(x)-y_{measured}(x))^2}{\sigma_y^2}$$
Can I just replace ##\sigma_y^2## with ##\sigma_x^2+\sigma_y^2##? The errors on x and y are not correlated. Thank you!
