The bootstrap, like the jackknife, is a technique for estimating standard errors. The idea is to usc Monte Carlo simulation, based on a non-parametric estimate of the underlying error distribution. The bootstrap will be applied to an econometric model describing the demand for capital, labor, energy, and materials. The model is fitted by three-stage least squares. In sharp contrast with previou...
The Win95/98/NT program FreeTree for computation of distance matrices and construction of phylogenetic or phenetic trees on the basis of random amplified polymorphic DNA (RAPD), RFLP and allozyme data is presented. In contrast to other similar software, the program FreeTree (available at http://www.natur.cuni.cz/~flegr/programs/freetree or http://ijs.sgmjournals.org/content/vol51/issue3/) can a...
Because our method dose not base on alignment, it is impossible to perform the samplingover-sites bootstrap or jackknife as in the standard methods. Our previous work has developed a bootstrap strategy which samples over proteins in the proteomes (see Ref. 13 in the main text for details). As a merit of this method, it can be used to test whether dropping or adding some genes will alter the tre...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
The use and design of prior distributions that reflect prior ignorance have long been controversial in statistics. The use of any prior distribution marks the difference between Bayesian and frequentist schools of thought. Disagreements regarding the design of prior distributions to reflect ignorance, and the interpretation of posterior distributions derived from such priors, have resulted in c...
