Exponential Smoothing
Exponential smoothing assists with change detection as it smoothes out the data. The benfits of exponential
smoothing are that it gives you smoother data (less noisy data) and the ability to forecast using trends and
seanolaity for time series data. Additionally, data can be made to be less noisy for more confidence in a
CUSUM change detection model, which will see in this assignment.
Let’s pull in the data again.

Data transformation
Holt winters exponential smoothing requires a time series input, so we need to transform the data into time
series data.
First, we transform the data table into a vector:
temps_vec <- as.vector(unlist(temps[,2:21]))
head(temps_vec)
## [1] 98 97 97 90 89 93
plot(temps_vec)
Then we transform into time series
We know from our data exploration that there are 123 days per cycle, that’s why frequency gets set to 123 and
starts at 1996.
temps_ts <- ts(temps_vec, start = 1996, frequency = 123)
head(temps_ts)

plot(temps_ts)
Visualise the time series using decompose
The function decomposes a time series into seasonal, trend and irregular components using moving averages.
Deals with additive or multiplicative seasonal component. This is a nice way to visualise the time series data
before running the Holt Winter exponential smoothing.

It is interesting to note that the trend compnent in the data signals that the temperatures in the later years do
seem to get hotter. We would need a method of change detection to prove that the increase has breached a
valid threshold.
Running Holt Winter exponential smoothing
A note on additive versus multiplicative exponential smoothing. Additive smoothing is appropriate when faced
with seasonality that is fairly constant. For example, every year sales decrease by 100 items in february due to
the month being shorter and this is fairly consistent. Conversely, multiplicative seasonality is more appropriate
for time series data where the seasonality is changing periodically and it is proportional to the base. For
example, sales in December every increases by 15% compared to November, but over the years it has
increased by a higher and higher percentage.
In this example, it makes more sense to use multiplicative as the seasonality seems to be changing and it is
proportional to the base.
