INTRODUCTION The aim of this study was to evaluate the effect of intra-canal calcium hydroxide (CH) remnants after ultrasonic irrigation and hand file removal on the push out bond strength of AH-26 and EndoSequence Bioceramic sealer (BC Sealer). METHODS AND MATERIALS A total of 102 single-rooted extracted human teeth were used in this study. After root canal preparation up to 35/0.04 Mtwo rot...

In this manuscript we present various robust statistical methods and show how to apply them in R using the WRS2 package. We elaborate on robust location measures and present robust t-test versions for independent and dependent samples. We focus on robust one-way and higher order ANOVA strategies including mixed designs (“betweenwithin subjects”). Finally, we elaborate on running interval smooth...

Bonferroni’s Adjustment (also known as Dunn’s procedure). This procedure is simple to use and can be applied in a wide variety of situations where alpha correction is needed (and is perhaps most appropriate for situations other than the post hoc situation discussed here). To obtain a corrected critical value the desired alpha is divided by the number of comparisons or tests performed and that v...

We provide lower bounds for the norms of embeddings between γ-weighted Anchored and ANOVA spaces of s-variate functions with mixed partial derivatives of order one bounded in Lp norm (p ∈ [1,∞]). In particular we show that the norms behave polynomially in s for Finite Order Weights and Finite Diameter Weights if p > 1, and increase faster than any polynomial in s for Product Order-Dependent Wei...

This handout describes the analysis of a repeated-measures experimental design with two crossed among-subjects factors and repeated-measures on a third (withinsubjects) factor. It presents the analysis described in the text: univariate ANOVA with the conservative F test, along with assessment of the validity of the model and with analysis of the effects. A later handout will present linear mixe...

The most-popular root canal filling materials for primary teeth are zinc oxide eugenol (ZOE), iodoform paste, and calcium hydroxide. Root canal filling materials need to be biocompatible with the periapical tissue. There are few papers which indicate the mechanism of cellular change of root canal filling materials. The purpose of the present study was to evaluate the cellular changes of a ZOE w...

Interactions occurring between Saccharomyces cerevisiae and two thermostable α-amylase producing strains (Bacillus amyloliquefaciens 04BBA15 and Lactobacillus fermentum 04BBA19) were analyzed by comparing their growth patterns obtained in isolation with those obtained in mixture. The difference between the patterns was assessed using analysis of variance (ANOVA) in order to measure how much the...

The age for the fastest marathoners is well investigated, but not the age and nationality of the fastest. We investigated the age of peak marathon performance for the annual top 100 women and men competing in four races of the "World Marathon Majors" (Boston, Berlin, Chicago and New York) and the "Stockholm Marathon" between 2000 and 2014 using mixed-effects regression analyses and one-way ANOV...

BACKGROUND Changing trends demonstrate that women, in a number of economically-developed countries, are drinking at higher levels than ever before. Exploring key targets for intervention, this study examined the extent to which underlying beliefs in relation to alcohol consumption predicted intentions to drink in three different ways (i.e. low risk drinking, frequent drinking and binge drinking...

The analysis of series of crop variety trials has a long history with the earliest approaches being based on ANOVA methods. Kempton (1984) discussed the inadequacies of this approach, summarized the alternatives available at that time and noted that all of these approaches could be classified as multiplicative models. Recently, mixed model approaches have become popular for the analysis of seri...
