Hello, Dogod11!
I'm not familiar with Time Series.
I've had to come up with my own theories.
An example of time series would be:
Then they say, this series can also be expressed as:
. .
How do they do it and why they develop the series?
It only makes sense if . . . the initial quantity is zero.
Then we have:
. .
And we see the pattern:
. .
which can be written: .
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
Why did they derive this formula?
So we can find, say, the 20th term
. . without cranking out the first 19 terms.
