1. Problem 1. Given a data set (X, Y), use the least squares techniques to find the best ftting curve y-/() within the exponential family v ab) where a,b ER. The data set is given by, where, χ-io, 0.2, 0.4, 0.6, 08, 09, 1, 12, 14, 1.6] y 2, 2.5, 3.1, 3.9, 4.8, 5.4, 6, 7.5, 9.3, 11.6] In particular: a) Going from the original data (x,Y) set to the transformed data set (X, Z) with z(Y)-In (Y), verify that Ir (X,Z)l 1, where r denotes the linear correlation coefficient; b) Find the best linear fit()-Bz+ A for the transformed data set (x, z) e) Prom the best linear fit, find the bent exponential ftting curve y(e) -ab for the original data set (x,Y). Hint: a eA and b- e
