Exponential Moving Average - Algorithm by TimeSeries

No algorithm description given

Takes a time series and returns the exponential moving average ( http://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average ). This can be used to smooth or denoise a time series. The user can optionally supply an alpha parameter (specifying how heavily the past is weighted) as second argument. If not supplied a default of 0.5 is used.

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.

To understand more about how algorithm permissions work, see the permissions documentation.

1. Type your input
