Abstract

Regression analysis can be done by parametric and nonparametric approach. The nonparametric approach does not assume an assumption compared to parametric. One nonparametric approach is the spline truncated. Spline is a polynomial piece that provides high flexibility. Spline modeling requires spline and knots. To determine the knots using General Cross Validation (GCV). In this study modeled the value of Jakarta Composite  Index (JCI). JCI provides benefits to know the overall stock price in the stock exchange Indonesia. In this study the best spline model is linear with three knots with R square is 94.34%. Keywords: Jakarta Composite’s Index, Spline truncated, GCV.

Abstract

Regression analysis can be approached by using parametric, semi-parametricand nonparametric regression approaches. One of nonparametric regressionapproach that great developed was Spline truncated, including for modelinglongitudinal data. Longitudinal data is data that consisting of several subjectswhich is each subject is observed repeatedly based on a certain time. Theadvantages of longitudinal data has provided more complexcityof  informationthan cross section and time series data. The spline approach was a segmentedpolynomial regression approach. Spline provides high flexibility due to the useof knot points. To determine the optimal knot points using Generalized CrossValidation (GCV). The principle of determining the optimum point of knot oflongitudinal data using spline truncated is basically the same as with Splinemethod  for cross section data, that is determination of knot point based on eachsubject. However, the estimation is done simultaneously so that each subject hasits own model. Keywords: Spline Truncated, GCV, Knot points.

Abstract

This study aims to analyze the student’s responses in writing action research proposals. The method  of this research is the descriptive quantitative.  The subject of this study was UT Semarang students 2018.1 in Pokjar Kaliwungu Kendal who took Action Research courses. The data collection technique used questionnaires by giving a set of questions or written statements to respondents to answer them. The results of the student’ s responses analysis before and after the Colaborative Writing model application showed that there was an increase in the average student’ s activeness because they were more enthusiastic in writing Classroom Action Research proposals by collaborating in writing with groups according to the developed teaching materials. Their tendency to more easily determine the topic of research using the Collaborative Writing model.Keywords: analyzing, writing research, collaborative writing, student’s responses
