The yield was measured after the harvest. Because the 3 rd method was not tested on the 4 th type of field (because of a lack of seeds), and the 2 nd method on the 4 th type of field (because of a hail storm), the experiment is a typical example of an unbalanced ANOVA. We have performed an ANOVA with interactions in order to determine the interactions between the types of methods used and the t...

The one-way random-effect ANOVA model is presented, and two simulated datasets are analyzed. and discussed from three points of view: (1) The standard ANOVA table, F test, and method-of-moments estimates of variance components, which can lead to negative estimates. (2) Maximum likelihood estimates of variance components. (3) Bayesian probability intervals for variance components based on flat p...

BACKGROUND Statistical tables are an important component of data analysis and reports in biological sciences. However, the traditional manual processes for computation and presentation of statistically significant results using a letter-based algorithm are tedious and prone to errors. RESULTS Based on the R language, we present two web-based software for individual and summary data, freely av...

We consider inferences in a one-way ANOVA model with equicorrelation error structures. Hypotheses of the equality of the means are discussed. A generalized F-test has been proposed by in the literature to compare the means of all populations. However, they did not discuss the performance of that test. We propose two methods, a generalized pivotal quantities-based method and a parametric bootstr...

Consider the one-way ANOVA problem of comparing the means m1; m2; . . . ; mc of c distributions F1…x† ˆ F…x ÿ m1†; . . . ; Fc…x† ˆ F…x ÿ mc†. Solutions are available based on (i) normal-theory procedures, (ii) linear rank statistics and (iii) M-estimators. The above model presupposes that F1; F2; . . . ; Fc have equal variances (ˆ homoscedasticity). However practising statisticans content that ...

introdouction: the aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3d) cone-beam computed tomography (cbct) scans. materials and methods: in this prospective cross-sectional study, cbct scans and lateral cephalograms of 35 subjects, taken within one wee...

background and aims. different materials have been used for root-end filling during surgical endodontic treatment. the aim of this in vitro study was to evaluate the dye penetration in different thicknesses of calcium enriched mixture (cem) cement as root-end filling material. materials and methods. following root canal filling in 70 extracted human single-rooted premolar teeth, the apical 3 mm...

the present study attempted the relative effect of explicit teaching of textual metadiscourse markers on esap reading comprehension performance of iranian university students through an awareness raising experiment. a sixty-item multiple choice esap reading comprehension test of accounting was developed and validated to act as the pre-test and post-test. the test included items for assessing sp...
