Hello, I've got a function f(x) with this function. For x in -2 : 2 i've generated a vector y with function values. There is also a data set and I've constructed an estimator which should find values similar to y. My question is, what is the best way to compare these vectors? A simple example y=1 and a sample size of 10. y = [1] 1 1 1 1 1 1 1 1 1 1 est = [1] -2.34465214 -1.85665524 -1.36865834 -0.88066144 -0.39266455 0.09533235 0.58332925 1.07132615 1.55932305 2.04731995 Kind regards, Koen
