Web13. If the trend is deterministic (e.g. a linear trend) you could run a regression of the data on the deterministic trend (e.g. a constant plus time index) to estimate the trend and remove it from the data. If the trend is stochastic you should detrend the series by taking first differences on it. The ADF test and the KPSS test can give you ...
WebFor deterministic models, test cases are often expressed as sequences of inputs and expected outputs.For nondeterministic systems, test cases can be represented as trees.
