| Summary: | 碩士 === 國立中央大學 === 統計研究所 === 94 === The Taiwan Railway has been a long standing history in Taiwan. The western part of the railway system plays an important role of short, medium, and long distance transportation in the South/North route. However, the feeling of passengers about the service of railway system can provide the information that the Taiwan Railway Administration (TRA) establishes a future operation policy.
This thesis is dedicated on the statistical analysis on satisfaction of various services such as transportation quality, ticket selling, customer support, and actual attendance provided by the TRA. Firstly, we offer the analysis of descriptive statistics to understand the situation of general information of passengers and their satisfaction about various service items provided by the TRA. Then we analyze the distinction of these items by the Ridit analysis for discovering the advantage and the inferiority of the TRA service , and hence we can find out which items having the advantage in the competition and others needed to be improved. Using chi-squared test of independence, chi-Square automatic interaction detection（CHAID）for filtering out the most affective variables of personal background, we establish the logistic regression model for the service items to look for the main factors that affect them most, and the results can be considered to improve the TRA's management in the future.
