In this paper, we assume the error distribution of one-way ANOVA as alpha-skew normal distribution. Alpha-skew gives us exibility for modelling data which has heavy tailness, skewness, bimodality and also symmetricity. We obtain maximum likelihood estimator model parameters test statistics based on these estimators. Monte Carlo simulation study states that estimators interest are more efficient...

In the SAS System, PROC MIXED offers users the possibility to perform analysis of complex data where assumptions of traditional analysis of variance (ANOVA) methods such as homogeneity of variance or independence of error terms might be violated. Thus, this procedure can be used to analyze data where the observations are assumed to come from a normal distribution but are correlated such as in l...

PURPOSE To determine the change in stability of single-stage, three different design of implant systems in humans utilizing resonance frequency analysis for early healing period (24 weeks), without loading. MATERIAL AND METHODS Twenty-five patients were included into this study. A total of 45 implants, three different design of implant systems (group A,C,R) were placed in the posterior maxill...
