%description
A web application for displaying, analysing and forecasting univariate
time series. Includes basic methods such as mean, naïve, seasonal naïve
and drift, as well as more complex methods such as Holt-Winters Box,G and
Jenkins, G (1976) <doi:10.1111/jtsa.12194> and ARIMA Brockwell, P.J. and
R.A.Davis (1991) <doi:10.1007/978-1-4419-0320-4>.
