All of audio as we know it is an attempt to be more and more perfectly linear.

That is known as the finger of God effect.

Now, at low redshifts, the expansion is linear.

In a given cosmological model, specified by values of different, omegas, or little w as well.

Once Z axis is at home, remove the bracket

But basically, sparse means you're closer to the lower bound, closer to linear.

One we assume that we have normal distributions in both variables X and Y. Two, we assume that we have a linear relationship between X and Y. And three, there's an assumption called homoscedasticity.

Now that's going to be fine if you have a dense graph, the number of edges is as high as n squared, then you're not really wasting anything in this representation.
