tslm : Fit a linear model with time series components
WebNov 17, 2014 · This means that the chosen model considers the presence of a stochastic trend rather than a deterministic trend, e.g. linear trend. As regards the coefficients, they are weights of past observations of the data (in this case of the first differences of the data). We may expect that these weights will decay or go to zero.
