WebTrend analysis partitions the sum of squares for the model into portions due to linear trend, quadratic trend, cubic trend, etc. If there are k groups it is possible to look at up to k - 1 trends, although often researchers combine together all trends above quadratic or cubic. WebIts complexity analysis reflects this more complicated structure. In contrast with many previous works, BoostBlackBoxSolve does not always succeed: its result can be wrong with a small given probability $\varepsilon $ , but the doubly logarithmic dependence of the complexity with respect to $\varepsilon $ is satisfactory.
