The difference between the observed points and the regression line points is?

Let's assume anything tangible or real have got to have volume. Even the smallest factor the skin subject of an electron or some thing could lie inside that. Mathematically, maybe there is no such thing as a minimal. Like this state of affairs: preserve strolling 1/2 the distance to a door. Mathematically, you will never attain the door. However at some point, you're going to now not be able to take a step small sufficient to do half the space. Finally you are going to reach the door. Fact does not always work perfectly with math, so the tiniest thing would have a diameter of .0000 i dont be aware of methods to do a repeting decimal however let's consider it's infinite 0's and a 1. 0.00000000000000001 you get the concept. It is unimaginable to assume that volume, but according to me, thats the closest factor to 0 that also has price. Anyways, it sounds as if in the actual world there are limits. Sub atomic particles are those limits. Yes they've a diameter or a length, however when they're break up, IF they may be able to be cut up, they're going to not be matter, and thus no longer exist.

C. The error term.

think of the difference as the error of your regression line not going through all of those points.
