This research aims to make a comparison between the non-parametric and semi-parametric method to estimate the random effects balanced panel data (longitudinal) model.
In order to achieve the purpose of the research, two methods: Local Linear Polynomial and the Nadaraya - Watson were used in the nonparametric estimation. For the semi-parametric estimation, the Profile Least Square method was used. It was concluded that the semi-parametric method gave better results than the non-parametric methods for estimating the random effect balanced Panel data (longitudinal) model and the sample sizes (n=50,100,200), and variances (σ^2=0.5,1,1.5 ).
Simulation experiments were formulated and the applying of the methods used in this research was verified using the average sum of squares error criterion for different sample sizes and levels of variance.

There have been many studies that have explored the quality of educational services. However, there has been insufficient focus on examining the impact of service quality assessment on the marketing aspects of educational institutions. Based on this premise, this study aims to investigate the role of service quality in private educational institutions in creating a positive electronic word of mouth [eWOM] that subsequently affects students\' willingness to enroll in one educational institution over others. Using a quantitative design, data were collected through an online electronic questionnaire published in the groups and channels of students from three private educational institutions in Basrah (Al-Maqil University, Basra University College, Al-Kunooze University College). A total of 301 responses were collected. The data were then analyzed, and hypotheses were tested using various statistical tools in the [Amos & SPSS] program. The results indicate that educational service quality and its dimensions (except for the reliability dimension) have a significant impact on students\' electronic word-of-mouth. These findings are crucial for educational institutions\' main decision-makers, as they highlight the importance of further improving the quality of educational services and effectively delivering it to students, which, in turn, influences their word-of-mouth on social networking sites and shapes the institution\'s image with the public.
