WebThe method of least squares gives a way to find the best estimate, assuming that the errors (i.e. the differences from the true value) are random and unbiased. Let us consider a simple example. Problem: Suppose we measure a distance four times, and obtain the following results: 72, 69, 70 and 73 units WebThe method of least square • Above we saw a discrete data set being approximated by a continuous function • We can also approximate continuous functions by simpler functions, see Figure 3 and Figure 4 Lectures INF2320 – p. 5/80
