Ray Ban AAA Sunglasses Rare Print Color Rayban-0518,suitable parser and modifying its output
Synchronous context-free grammars (SCFGs) can be learned from parallel texts that are annotated with target-side syntax, and can produce translations by building target-side syntactic trees from source strings. Ideally, producing syntactic trees Sunglasses Ray Ban AAA Black Rayban-3404 would entail that the translation is grammatically well-formed, but in reality, this is often not the case. Focusing on translation into German, we discuss various ways in which string-to-tree translation models over- or undergeneralise. We show how these problems can be addressed by choosing a suitable parser and modifying its output, by introducing linguistic constraints that enforce morphological agreement and constrain subcategorisation, and by modelling the productive generation of German compounds. A new class of extended Birnbaum–Saunders Ray Ban AAA Sunglasses Rare Print Color Rayban-0518 regression models is introduced. It can be applied to censored data and be used more effectively in survival analysis and fatigue life studies. Maximum likelihood estimation of the model parameters with censored data as well as influence diagnostics for the new regression model are investigated. The normal curvatures for studying local influence are derived under various perturbation schemes and a martingale-type residual is considered to assess departures from the extended Birnbaum–Saunders error assumption as well as to detect outlying observations. Further, a test of homogeneity of the shape parameters of the new regression model is proposed. Two real data sets are analyzed for illustrative purposes.
