Research paper thumbnail of Forecasting Tourist Arrivals to Sri Lanka Using Seasonal ARIMA

Forecast of the tourist arrivals can provide reliable estimates of tourist related product and services such as hotel rooms, car rentals, and a number of visitors to places of tourist attractions, etc. In particular, short term tourist arrival forecasts are very vital for optimal pricing of tourist related services such as air tickets and hotel rooms. However, we can find only a few research articles dealing with short term forecasting of international tourist arrivals to Sri Lanka. Therefore, we attempted to forecast monthly tourist arrivals to Sri Lanka using customized model building procedure, statistical time series modeling techniques. We found that general seasonal ARIMA model ARIMA as a suitable model to forecast monthly international tourist arrivals to Sri Lanka.

The study follows logit analysis using Behavior Risk Factor Surveillance Systems (BRFSS) survey data of 2018. The individual data reported for the states were used for the analysis. The statistical package of STATA was used for the analysis. The analytical results show that physical exercise (EXER), number of sleeping hours (SLEP), and education (EDUC) play a major role in combatting obesity. Also, the impact of smoking (SMOK), alcohol consumption (DRNK), and obesity -related diseases ((DISE). The large differences in value between Colorado and Mississippi indicate the significance of these variables and how they could be used in Mississippi. Thus, Mississippi needs to go for efficient and effective policy i...

We analyze the existence of a moving attractor for a semi-linear parabolic equation. The analysis is carried out by using a coordinate transformation to obtain the equation in moving coordinates and the contractions of the solutions to traveling wave solutions. We show that a moving attractor exists if the linearized equation on the moving frame follows a stability condition. Application of moving attractor in long term error analysis is discussed with numerical examples.

Research paper thumbnail of Investigation the Association of Some Variables with Mathematics Achievement Gap Between Rural and Urban Jordanian Students

Journal of Education and Practice, 2020

Due to nested structure of the TIMSS data, hierarchical linear model, was used in this study. To this end the data for 6541 students in 232 schools was analyzed. According to study findings 21.4% of total variation in mathematics achievement was due to the differences between schools. Moreover, the study results revealed that school emphasis on academic success, and school discipline problems as school-level variables were discovered to have statistically significant effect on mathematics achievement gap between urban - rural students in Jordan. Furthermore, concerning student-level variables, student like learning mathematics was the only associated significantly with the urban-rural gap in mathematics achievement. The study recommended the necessity of enhancing the capabilities of rural schools to focus on s...

Do the student factor: parents' education level significant predictor of student math-achievement? 2. Do the school factors: principals' perception of school climate, availability of school resources for mathematics instructions, and good school and class attendance explain differences in mathematics achievement among schools? 3. Do school factors reduce the effect of student factors in student math-achievement? Literature Review Research has indicated a positive relationship between education level of the parents and the student performance in mathematics (Education Matters 2004).
