Theoretical distribution of truncation lengths in incremental truncation libraries

Biotechnology and Bioengineering, 2003
AbstractIncremental truncation is a method for constructing libraries of every one base pair truncation of a segment of DNA. Incremental truncation libraries can be created using a time‐dependent nuclease method or through the incorporation of α‐phosphothioate dNTPs by PCR or by primer extension (THIO(pcr) truncation and THIO(extension) truncation ...

Anytime Truncated D* : Anytime Replanning with Truncation

Proceedings of the International Symposium on Combinatorial Search, 2021
Incremental heuristic searches reuse their previous search efforts to speed up the current search. Anytime search algorithms iteratively tune the solutions based on available search time. Anytime D* (AD*) is an incremental anytime search algorithm that combines these two approaches.

A post-truncation parameterization of truncated normal technical inefficiency [PDF]

Journal of Productivity Analysis, 2014
In this paper we consider a stochastic frontier model in which the distribution of technical inefficiency is truncated normal. In standard notation, technical inefficiency u is distributed as N +(μ, σ 2). This distribution is affected by some environmental variables z that may or may not affect the level ...

Un-Truncating VARs [PDF]

SSRN Electronic Journal, 2013
Macroeconomic research often relies on structural vector autoregressions to uncover empirical regularities. Critics argue the method goes awry due to lag truncation: short lag-lengths imply a poor approximation to DSGE-models. Empirically, short lag-length is deemed necessary as increased parametrization induces excessive uncertainty.

Truncated Simes Tests

Biometrics, 2019
Abstract It is known that the one-sided Simes’ test controls the error rate if the underlying distribution is multivariate totally positive of order 2 (MTP2), but not in general. The two-sided test also controls the error rate when the coordinate absolute value has an MTP2 distribution, which holds more generally. We prove mathematically

Pearson diagrams for truncated normal and truncated Weibull distributions

Biometrika, 1985
SUMMARY The skewness and kurtosis of doubly truncated normal distributions and right truncated Weibull distributions are studied. The former lie in the type I region and the latter in type I, type III or type VI regions in the Pearson system of distributions.
