Question

I'm trying to run a time series that proves a correlation between two surveys that each have 10 months of data. What would I use in R to try and prove correlation?

Answer 1

You may draw the acf and pacf plots of the time series data. For that use the command acf(model name) and pacf(model name) respectively. You get the generated plots with several vertical lines and two blue colored horizontal lines. If all the vertical lines lie in between the two blue horizontal lines, it indicate that the data does not have auto correlation. If the vertical lines lie beyond the two blue horizontal lines, it shows that the data exhibits serial correlation.
