Here is a tutorial on how to use R programming software to carry out time series analysis
To load data set from the package “fma”, use the commands:
>data (package=fma) This instantly loads the pre existing data sets in the package. To load the data set regarding sales of one family houses, use the command: >data (hsales) To print the data: >hsales
Now, form a time series from the data using the command:
>timeseries <- ts (hsales, frequency=12, start=1973) Here, the variable name is “timeseries”, feequency is 12(because it is monthly data), and start=1 (since the data starts from 1973) Now, print the series: >timeseries
To plot the time series, use the command: >plot.ts (timeseries, main=”Sales of one family houses”)
To decompose the time series into its components, use the command in R statistical software: >timeseriescomponents <- decompose (timeseries) Print the decomposed series, >timeseriescomponents
You can also plot the decomposed time series components using R software >plot (timeseriescomponents)
