Applying the Thorne-Kishino-Felsenstein model to sequence evolution on a star-shaped tree
Stochastic models that allow site substitutions, insertions and deletions provide a useful framework for a statistical approach to DNA sequence evolution. Such a model, and recursions to calculate the probability of evolving two sequences, have been known for almost a decade. In this paper we show how the pairwise recursions can be generalised to a 3-sequence tree, and more generally to a r-seq...
متن کاملGibbs Sampler for Statistical Multiple Alignment
For a set of sequences, related by a binary tree, that have evolved according to the Thorne-Kishino-Felsenstein model, a Gibbs sampler is presented for simulating the ancestral sequences and their alignments. The updating step consists in updating the ancestral sequence and its three alignments within a 3-star tree. We compare the Gibbs sampler with the algorithm suggested recently by Holmes an...
متن کاملUsing guide trees to construct multiple-sequence evolutionary HMMs
MOTIVATION Score-based progressive alignment algorithms do dynamic programming on successive branches of a guide tree. The analogous probabilistic construct is an Evolutionary HMM. This is a multiple-sequence hidden Markov model (HMM) made by combining transducers (conditionally normalised Pair HMMs) on the branches of a phylogenetic tree. METHODS We present general algorithms for constructin...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
A Tree Sequence Alignment-based Tree-to-Tree Translation Model
This paper presents a translation model that is based on tree sequence alignment, where a tree sequence refers to a single sequence of subtrees that covers a phrase. The model leverages on the strengths of both phrase-based and linguistically syntax-based method. It automatically learns aligned tree sequence pairs with mapping probabilities from word-aligned biparsed parallel texts. Compared wi...
