Comparison of statistical techniques  for forecasting The Stock Exchange of Thailand index
Comparison of statistical techniques for forecasting The Stock Exchange of Thailand index

The purpose of this study is to compare four forecasting methods on SET Index SET 50 Index and SET 100 index. These methods are Simple Exponential Smoothing Holt’s Method Box-Jenkins Method and Regression Analysis. Two sets of Index data were used in this study. The first one used as a training set was collected at the end of each day from January 2 2008 to September 30 2011. The other one used as a testing set was collected at the end of each day from October 3 2011 to October 14 2011. The diagnostic check was used to test each method. The MAE MSE and MAPE from each method shows that Box-Jenkins is more appropriate to the forecasting of SET Index SET 50 Index and SET 100 Index because its MAE MSE and MAPE are fairly low and have no autocorrelations. This leads to the conclusion that the appropriate models for forecasting of SET Index SET 50 Index and SET 100 Index are ARIMA (212) ARIMA (213) and ARIMA (213) respectively. The most stock market indices are correlated to SET Index SET 50 Index and SET 100 Index is Composite Index of Indonesia

Risk factors for dengue fever in Thailand using mathematical Generalized Estimating Equation (GEE)
Risk factors for dengue fever in Thailand using mathematical Generalized Estimating Equation (GEE)

The objectives of this research were to investigate risk factors for Dengue fever in Thailand and to select an appropriate model. The generalized estimating equation (GEE) whose dependent variable has a Poisson distribution and a negative binomial distribution were studied. The secondary data consisting of the number of Dengue fever patients rainfall average temperature forest area household income were collected. Regions and seasons were also considered. The research found that the GEE whose dependent variable has a negative binomial is more appropriate to be used for Dengue patient data analysis. Central region and the season during Feb-Apr were assigned to be reference groups. Risk factors for Dengue fever were rainfall (Relative Risk (RR) = 1.0009) average temperature (RR = 1.1736) forest area (RR = 1.0482) southern region (RR = 2.7390) eastern region (RR = 2.0489) western region (RR = 1.4051) the season during May-Jul (RR = 3.0526) and Aug-Oct (RR = 3.2677)

The effects of pulp and fiber crops that affect the printing surface through for packaging
The effects of pulp and fiber crops that affect the printing surface through for packaging

The study researches the effects of pulp and fiber crops that affect the printing surface through For packaging. The purpose of the study of plant fiber pulp.Compare the quality of the pulp fiber of plants that affect the printing surface throughThe data can be used in the design of appropriate packaging. And to compare the effects of the packaging structure of plant fiber pulp. Population and sample used in the study include the printing surface through Pulp and paper plants 5 types of equipment used in fiber research. The pulp and fiber crops. By manufacturers or those with knowledge of print. A uniform test. Clarity and completeness of the printing sector. Spec with a photometer in a satisfactory printing on pulp fibers through the plant by the manufacturers or those with knowledge of print. And the satisfaction of the pulp fiber packaging plant. By manufacturers or those with knowledge of the packaging. The research concluded that. Comparison of pulp fibers from plant samples 40 of them are featured on pulp paper suitable for printing in the most average of 4.6. The analysis compared the print quality of the pulp through a fiber plant. The test is simple and consistent. Clarity and completeness of the printing sector. The colors that appear on printed material including five kinds of color have always been smooth with differences not exceeding 5 shows the results in a value that can be seen as well. Comparison of satisfaction on the pulp paper and printing through the most appropriate. Is satisfactory in most average 4.65. Comparison of satisfaction packaging pulp paper plant fiber 5 and found that the packaging 1 and Type 3 are the scores remained level. The packaging is an average of 4.08 and packaging Type 3 has an average of 4.04. This research concluded that Pulp paper and print quality on the most appropriate.Is satisfactory in most The properties of the pulp. Print quality. As well as satisfaction with the quality printing. While pulp and pineapple pulp the elephant has a surface that is not strong. I withdrew the paper fibers of the time. Should improve the quality of pre-printed paper surface.
