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...

Preeious metal alloys bondcd by the adhesive r'esin were thermocycled O, 1,OOO, 2,OOO, or 4,OOO times in water between 4 and 60°C , and tensile bend strengths were measurecl. Debonded metal surfaces after the tensile test were analyzed based on an area of cohcsive failure. Three-way ANOVA revealed that all the three parameters adherend, adhesive rnonemer, and nurnber of thermal cycles exhibited...

After rejecting the null hypothesis in analysis of variance, next step is to make pairwise comparisons find out differences means. The purpose this paper threefold. foremost aim suggest expression for calculating decision limit that enables us collect test and one step. This proposed as ratio between square each treatment within sum squares all treatments. second obtain sampling distribution un...

Present investigation is an attempt to examine the affective components i.e. anxiety and depression among the heroin addicts (N=50) and its comparison with their normal counterparts (N=50). Anxiety Scale and Beck-Depression Inventory (BDI) tests were administered on both the samples of heroin addicts and normal groups. Test Scores were analysed using one way ANOVA. The results showed significan...

Materials and methods Medical records of 3009 subjects who attended the Centre between 1984 and 1995 and 2158 age–matched individuals, are accessible. A pilot case-control study on 12 treated subjects and 10 controls, aged 31.4 (27 – 37) years, Cobb 35.4 (10 54°), was conducted. Total lung capacity and spirometry, physical activity, back pain, self-functioning, quality of life and patients’ att...

decision encoding. Two types of measurements were used for this evaluation. 439 First, we compared the decision SLR coefficients of decision neurons across the three 440 areas (ad, Figure 7A). Moreover, we related the strength of the decision processing of 441 these brain areas to their encoding strength of stimulus intensity, by intensity selective 442 neurons (aint, Figure 7B). We calculated ...
