Holt's trend methods

Holt's local trend method is implemented in the holt() function:

> holt(y, h = 10, ...)

Here, you will apply it to the austa series, which contains annual counts of international visitors to Australia from 1980-2015 (in millions). The data has been pre-loaded into your workspace.

Produce 10 year forecasts of austa using Holt's method. Set h accordingly.
Use the summary() function to view the model parameters and other information.
Plot your forecasts using the standard time plotting function.
Use checkresiduals() to see if the residuals resemble white noise.
