Multivariate flexible least squares analysis of hydrological time series
Abstract Models with coefficients which change with time can be developed by using Kalman filter techniques and these have been applied to model river flow, rainfall and other hydrological time series. However, application of Kalman filter techniques requires assumptions about the statistics of processes and state variables which may depend on unknown factors, and these assumptions may not be v...
متن کاملA New Framework for Distributed Multivariate Feature Selection
Feature selection is considered as an important issue in classification domain. Selecting a good feature through maximum relevance criterion to class label and minimum redundancy among features affect improving the classification accuracy. However, most current feature selection algorithms just work with the centralized methods. In this paper, we suggest a distributed version of the mRMR featu...
متن کاملChangepoint Detection in Periodic and Autocorrelated Time Series
Undocumented changepoints (inhomogeneities) are ubiquitous features of climatic time series. Level shifts in time series caused by changepoints confound many inference problems and are very important data features. Tests for undocumented changepoints from models that have independent and identically distributed errors are by now well understood. However, most climate series exhibit serial autoc...
متن کاملA Changepoint Detection Method for Profile Variance
A wavelet-based changepoint method is proposed that determines when the variability of the noise in a sequence of functional profiles goes out-of-control from a known, fixed value. The functional portion of the profiles are allowed to come from a large class of functions and may vary from profile to profile. The proposed method makes use of the orthogonal properties of wavelet projections to ac...
