A method and system for analyzing competition results is disclosed, the method comprising providing a probability model to analyze competition results including both information about options used for a competition process, and rank information of competition participants; and determining a first parameter about a pure ability of each competition participant, and a second parameter about advantages and disadvantages of the option used for the competition process by analyzing the competition results using the probability model, wherein the first and second parameters are determined by calculating a prior distribution of the second random variable, calculating a likelihood function of the second random variable, and estimating the first and second parameter through the use of the prior distribution of the second random variable and the likelihood function. This method and system can estimate the advantages and disadvantages of the options used for the process of competition, whereby the estimated advantages and disadvantages of the options are reflected on the design of competition or the adjustment of options when designing the competition such as the game, to thereby maximize the interest in competition.
