This paper presents a method of the statistical modeling by which the epistemic uncertainty of the data can be reduced. Firstly, probability distributions for of the modeling parameters are shown for typhoon pressure fields to estimate reproducibility of the observed parameters. Then, evaluate the variance of the central pressure and gradient wind speed using the different number of the data and estimation method of the distribution parameters.
