We make a table.
it shows this scatterplot.
Now, assume I the graph is degree 6. just plot the degree 6 polynomial formula
You see R^2 is = 1. This is 100% accuracy.
It also tells you what the numbers are. a = 0.0210704
and this is the graph:
Requires all terms
now, see if I remove the g, any of the terms, it breaks.
The graph looks like shit
the stats are bad too.
