Usage

Try mave out on an example file using any of the methods below. Each of these will build a model on the dataset contained in ex3.csv, the difference between the three approaches is in how the post-retrofit period is defined.

mave ex3.csv 

This assumes the last 25% of the file represents the postretrofit period as the default value of the 'test_size' argument is 0.25.

mave ex3.csv -ts 0.45

This uses the 'ts' or 'test_size' argument to explicitly specify the fraction of the file to use. In this example the last 45% of the file represents the postretrofit period.

mave ex3.csv -cp "1/11/2013 00:00"

This example uses the 'cp' or 'changepoint' argument to explicitly define the date at which the post retrofit period begins. This overrides the 'test-size' value. In this case all data on or after Jan 11, 2013 at 00:00 represents the post-retrofit period.

Mave has many configurable options (e.g. -v for verbose output) which can be passed as command line arguments or using a separate configuration file. The configuration file also allows many other advanced modeling options, such as specifying multiple different periods in the file to use as pre-retrofit or post-retrofit, or to ignore entirely. Review the wiki documentation section on 'pre-processing' or 'configuration' for more details.
