Rear view. Cheque truncation (check truncation in American English) is a cheque clearance system that involves the digitization of a physical paper cheque into a substitute electronic form for transmission to the paying bank. The process of cheque clearance, involving data matching and verification, is done using digital images instead of paper ...
Cheque Truncation System (CTS) or Image-based Clearing System (ICS), in India, is a project of the Reserve Bank of India (RBI), commenced in 2010, for faster clearing of cheques. [1] CTS is based on a cheque truncation or online image-based cheque clearing system where cheque images and magnetic ink character recognition (MICR) data are ...
In probability and statistics, the truncated normal distribution is the probability distribution derived from that of a normally distributed random variable by bounding the random variable from either below or above (or both). The truncated normal distribution has wide applications in statistics and econometrics.
Truncated regression model. Truncated regression models are a class of models in which the sample has been truncated for certain ranges of the dependent variable. That means observations with values in the dependent variable below or above certain thresholds are systematically excluded from the sample. Therefore, whole observations are missing ...
Catastrophic cancellation. In numerical analysis, catastrophic cancellation[1][2] is the phenomenon that subtracting good approximations to two nearby numbers may yield a very bad approximation to the difference of the original numbers. For example, if there are two studs, one long and the other long, and they are measured with a ruler that is ...
Model order reduction. Model order reduction (MOR) is a technique for reducing the computational complexity of mathematical models in numerical simulations. As such it is closely related to the concept of metamodeling, with applications in all areas of mathematical modelling.
Note that winsorizing is not equivalent to simply excluding data, which is a simpler procedure, called trimming or truncation, but is a method of censoring data. In a trimmed estimator, the extreme values are discarded; in a winsorized estimator, the extreme values are instead replaced by certain percentiles (the trimmed minimum and maximum).
The relation between local and global truncation errors is slightly different from in the simpler setting of one-step methods. For linear multistep methods, an additional concept called zero-stability is needed to explain the relation between local and global truncation errors.
