Autocorrelation technique
Hi there! So, autocorrelation technique is a way to see if there's a pattern or relationship between different data points that are close together in time.
Let's imagine you have a friend who likes to count the number of cars that pass by their house every day. They write down the number of cars they see at the same time every day for a month.
Now, if we put all these numbers into a graph, we might see some patterns. For example, maybe there are more cars during rush hour (when people are going to and coming back from work). But maybe there are also some days where there are more cars than usual even though it's not rush hour.
Autocorrelation helps us figure out if these patterns are just random or if there's something actually causing them. It does this by looking at how similar the numbers are to each other when they're close together in time.
So, for example, if there are more cars on Monday than on Sunday, we might expect there to be more cars on Tuesday than on Monday because they're close together in time. Autocorrelation can help us see if that's actually the case.
Overall, autocorrelation is a way to help us understand if there's a relationship between things that happen close together in time, like the number of cars that pass by your friend's house.
