[10e] Name this statistical technique whose “linear” type attempts to find a line of best fit.
ANSWER: regression [accept linear regression]
[10m] Most linear regression algorithms typically seek to minimize the sum of the values of this function on the residuals.
ANSWER: square [accept ordinary least squares]
[10h] This man and Gauss name a theorem stating that OLS regression has minimum variance among unbiased estimators. The Metropolis-Hastings algorithm uses a structure named for this mathematician in Monte Carlo simulations.
