this study aimed at comparing the effect of self-controlled feedback with 100% frequency on motor skill learning in children. 60 children (11.1±0.86 yr) were selected randomly and based on their pretest results divided into same three groups of 100% feedback, self-controlled and yoked. in the acquisition phase, subjects completed 120 trials. at the end of the second day, subjects performed a 10...

It is shown in detail how recent advances in multiple-output and projectional quantile regression open the door to exact computation of many inferential statistics based on projection pursuit. This is also illustrated on a few examples including new regression generalizations of multivariate skewness, kurtosis and projection depth. Note: The following files were submitted by the author for peer...

Complex longitudinal data are commonly analyzed using nonlinearmixed-effects NLME models with a normal distribution. However, a departure fromnormalitymay lead to invalid inference and unreasonable parameter estimates. Some covariates may be measured with substantial errors, and the response observations may also be subjected to left-censoring due to a detection limit. Inferential procedures ca...
