The least squares method is a statistical technique used in regression analysis to find the best trend line for a data set on a graph. Deriving the mean and variance of the least squares slope estimator in simple linear regression The short answer is that LS means (or more modernly, estimated marginal means) are incredibly useful with experimental data.
