doing Time Series Analysis.This will be a series of Exercises and I urge you to take it in series
Please install the package and load the library before starting
Answers to these exercises are available here.
Install Forecast package ,1st step in any analysis is to see the data , use autoplot to plot the gold data set
available in forecast package .
Find the outlier in the gold data .Find how far its from the median
use ggseasonalplot to plot the gas data . See how each year stack with each other
Now I want to plot the gas data for year 1990 and after .How do I achieve that .
ggseasonalplot can be used to see seasonal plots as polar coordinates , plot the same data as above but use
polar coordinates instead .
How can I see monthly time series of the gas price
Hint use monthplot or ggsubseriesplot
For a timeseries ,we can find the dominant frequency of that time series and use it to our analysis .How to
find the frequency of gas data (assume that its a long /big data and you dont have a clue of the frequency)
