These pairs are your observations, shown as green circles in the figure. For example, the leftmost observation has the input 𝑥 = 5 and the actual output, or response, 𝑦 = 5. The next one has 𝑥 = 15 and 𝑦 = 20, and so on.

The dot product is a measure of how similarly directed the two vectors are. For example, the vectors (1,1) and (2,2) are parallel. If you compute the angle between them using the dot product, you will find that θ = 0. redhead electric water smoker manual
