Cyst and tumor in oral cavity are seriously noticed by health experts along with increasing death cases of oral cancer in developing country. Early detection of cyst and tumor using dental panoramic image is needed since its initial growth does not cause any complaints. Image processing is done by mean for distinguishing the classification of cyst and tumor. The results in previous studies about classification of cyst and tumor were done by using a mathematical computation approach namely supports vector machine method that have still not satisfied and have not been validated. Therefore, in this study we propose a method, i.e., nonparametric regression model based on local polynomial estimator that can be improve the classification accuracy of cyst and tumor on human dental panoramic image. By using the proposed method, we get the classification accuracy of cyst and tumor, i.e., 90.91% which is greater than those by using the support vector machine method, i.e., 76.67%. Also, in validation process we obtain that the nonparametric regression model approach gives a significant Press's Q statistical testing value. So, we conclude that the nonparametric regression model approach improves the classification accuracy and gives better outcome to classify cyst and tumor using dental panoramic image than the support vector machine method.

Background : A lack of moral development might increase negative moral behavior. Drama, as a part of role-play, can stimulate the moral development of children aged 8-9 years.Objective : The purpose of this study is to explain the effect of role-play on the moral development of children aged 8-9 years Method : This research applied pre-experimental one-group pre-post test design. The population in this study was children aged 8-9 years with a total of 47 children. A sample of 15 respondents was taken using purposive sampling. The independent variable in this study is role-play stimulation, while the dependent variable is the moral development of children aged 8-9 years. Data collection was done using observation sheets, then analyzed using Wilcoxon Signed Rank Test with significance α = 0.05.Result: Wilcoxon Signed Rank Test shows that stimulation through role-play can influence the moral development of children aged 8-9 years with p = 0.001. Conclusion:The results of this study conclude that role-play stimulation can improve children's moral development.

“…Next, there are researchers who have discussed estimators in SR models; for examples [28,29] discussed smoothing techniques for estimating SR models; [30] used a spline estimator for determining the number of knots and their locations based on statistical criteria; [31] used an iterative weighted partial spline least squares estimator to estimate longitudinal SR model; [32] used a local linear estimator for designing the standard growth chart of children; [33] predicted GDP in Turkey using a SR model approach; [34] discussed a SR model applied to censored data; [35][36][37] discussed smoothing spline in SR models; [38] used bias-correction technique to construct the empirical likelihood ratios for estimating semiparametric model. However, those researchers discussed estimators in uni-response semiparametric regression (USR) models only.…”

Consistency and Asymptotic Normality of Estimator for Parameters in Multiresponse Multipredictor Semiparametric Regression Model

et al. 2022

A multiresponse multipredictor semiparametric regression (MMSR) model is a combination of parametric and nonparametric regressions models with more than one predictor and response variables where there is correlation between responses. Due to this correlation we need to construct a symmetric weight matrix. This is one of the things that distinguishes it from the classical method, which uses a parametric regression approach. In this study, we theoretically developed a method of determining a confidence interval for parameters in a MMSR model based on a truncated spline, and investigating asymptotic properties of estimator for parameters in a MMSR model, especially consistency and asymptotic normality. The weighted least squares method was used to estimate the MMSR model. Next, we applied a pivotal quantity method, a Cramer–Wold theorem, and a Slutsky theorem to determine the confidence interval, investigate consistency, and asymptotic normality properties of estimator for parameters in a MMSR model. The obtained results were that the estimated regression function is linear to observation. We also obtained a 100(1 − α)% confidence interval for parameters in the MMSR model, and the estimator for parameters in MMSR model was consistent and asymptotically normally distributed. In the future, these obtained results can be used as a theoretical basis in designing a standard toddlers growth chart to assess nutritional status.
