kandi X-RAY | moving-averages Summary
When looking at trends over time, be it in the stock market, biological data, or log data, a moving average is a useful tool. It’s defined as taking a stream of numeric data (let’s call this an array of integers, n) and returning a new array which is the average of every window of size k over that array. There are more than one approaches to moving averages, but for this use case, we'll only consider SMA (simple moving average).

QUESTION
Scenario:
I want to calculate the moving average for sales amount for the entire month that has taken place SO FAR. Each month has a different number of days. If the sales_amount is 0, that means that person has the day off and I need to ignore that value.

since you are not interested in0
also you have an extra comma before the ROWS
QUESTION
I'm trying to follow this tutorial to calculate SMA: https://www.datacamp.com/community/tutorials/moving-averages-in-pandas
I would like to get the SMA for all values but I'm only getting 5. I have 17 values in the frame that I want to get values for. If I increase the rolling window I am not getting any values at all for SMA, why is that?
Thanks for any help as I'm new to Pandas
...ANSWER
Answered 2020-Jul-29 at 21:30When calculating a moving average, you need n
samples for it, which is the size of your moving window. Since you've set window=4
, then you need 4 samples for your average to be computed. That being said, these NaN
values just show that, in that point, there is not enough data to compute MA with window size = 4.
