)

## Arguments

tslist a list of time series a vector of models to compute whether the time series is from mcomp or other function to calculate the accuracy measure, the arguments for the accuracy function should be training, test and forecast forecast horizon number of measures calculated by a single function if the argument is TRUE, forecasts from each series are saved

## Value

a list with accuracy matrix, vector of arima models and vector of ets models
