    How Do OLS and LAD Regression Methods Differ?

    Hi I'mwondering what's the difference between least squares method with least absolute deviation method. Assume we have y=ax+b+s where s isdeviation. Is the step to calculate even a and b is different. I read that those two methods are almost the same but hardly found a real good explanation...

    How Do You Optimize a and b in Linear Regression for Minimal Deviation?

    Homework Statement I've been given a set of data x 0 0.5 0.7 1.5 1.75 y 0.5 0.72 0.51 1.5 1.63 Given y=ax+b for this data points of linear model, I have to 1. minimize the sum of the absolute values of deviations between experimental value of Y and value predicted by the...
