First, we propose a new type of marginal distribution estimator, named as a self-consistent estimator (SCE) and investigate its properties. Second, we propose several new approaches to compare two interval-valued samples, and also propose a procedure to test the stochastic order between two samples. In interval-valued data, the variable of interest is provided in the form of a two-dimensional vector of lower and upper bounds, not a single value. It is of interest to represent interval-valued data with a univariate random variable/marginal distribution. Two estimators, the empirical histogram estimator, and nonparametric kernel estimator have been proposed for the estimation of the marginal histogram in the literature. In the first part of the thesis, we define a new marginal representation, named as self-consistent marginal, for interval-valued data, and propose an SCE to estimate it. In the second and third parts of the thesis, we discuss how to compare two samples of interval-valued data. One is about the equality of two samples, and the other is about the stochastic order between two. First, to test equality, we consider four methods. Two are based on the existing approach for bivariate data, and the other two are newly proposed based on the univariate marginalization of interval-valued data. Second, to test the stochastic order, we propose a test statistic which belongs to U-statistic and derive its asymptotic null distribution. We conduct a comprehensive numerical study to investigate the performance of the newly proposed methods along with the existing methods. We further illustrate the advantages of the proposed methods over the existings by applying to empirical examples.๋ณธ ๋…ผ๋ฌธ์€ ๊ตฌ๊ฐ„์ž๋ฃŒ ๋ถ„์„์— ๊ด€ํ•œ ์„ธ ๊ฐ€์ง€ ์ฃผ์ œ๋กœ ๊ตฌ์„ฑ๋œ๋‹ค. ์ฒซ์งธ, ๊ตฌ๊ฐ„์ž๋ฃŒ์— ๋Œ€ํ•œ ์ž๊ธฐ์ผ์น˜ ๋ถ„ํฌ ์ถ”์ •๋Ÿ‰์„ ์ œ์‹œํ•˜๊ณ  ๋™ ์ถ”์ •๋Ÿ‰์˜ ์„ฑ์งˆ์— ๋Œ€ํ•˜์—ฌ ์‚ดํŽด๋ณธ๋‹ค. ๋‹ค์Œ์œผ๋กœ๋Š”, ๊ตฌ๊ฐ„์ž๋ฃŒ๋กœ ์ด๋ฃจ์–ด์ง„ ๋‘ ๊ฐœ์˜ ํ‘œ๋ณธ์„ ๋น„๊ตํ•˜๊ธฐ ์œ„ํ•œ ์ƒˆ๋กœ์šด ๋ฐฉ๋ฒ•์„ ์ œ์•ˆํ•˜๋Š” ํ•œํŽธ ๋‘ ํ‘œ๋ณธ์˜ ํ™•๋ฅ ์  ์ˆœ์„œ๋ฅผ ๊ฒ€์ •ํ•˜๋Š” ๋ฐฉ๋ฒ•์„ ์ œ์‹œํ•œ๋‹ค. ๊ตฌ๊ฐ„์ž๋ฃŒ์—์„œ๋Š” ๊ด€์‹ฌ ์žˆ๋Š” ๋ณ€์ˆ˜๊ฐ€ ํ•˜๋‚˜์˜ ๊ฐ’์ด ์•„๋‹Œ ํ•˜ํ•œ๊ณผ ์ƒํ•œ์˜ 2์ฐจ์› ๋ฒกํ„ฐ ํ˜•ํƒœ๋กœ ์ฃผ์–ด์ง„๋‹ค. ์ด๋ ‡๊ฒŒ 2์ฐจ์› ๋ฒกํ„ฐ๋กœ ์ด๋ฃจ์–ด์ง„ ๊ตฌ๊ฐ„์ž๋ฃŒ๋ฅผ ๋‹จ์ผ ๋ณ€๋Ÿ‰์œผ๋กœ ํ‘œํ˜„ํ•˜๋Š” ๋ฐฉ๋ฒ•์„ marginalization์ด๋ผ๊ณ  ํ•˜๋ฉฐ, ๊ธฐ์กด ์—ฐ๊ตฌ์—์„œ๋Š” marginal ํžˆ์Šคํ† ๊ทธ๋žจ์— ๊ธฐ๋ฐ˜์„ ๋‘” ๋ฐฉ๋ฒ•๋“ค์ด ์ฃผ๋กœ ์ œ์•ˆ๋˜์—ˆ๋‹ค. ์ด์— ๋ณธ ๋…ผ๋ฌธ์˜ ์ฒซ ๋ฒˆ์งธ ๋ถ€๋ถ„์—์„œ๋Š” ์ƒˆ๋กœ์šด marginalization ๋ฐฉ๋ฒ•๋ก ์„ ์ •์˜ํ•˜๊ณ  ์ด๋ฅผ ์ถ”์ •ํ•˜๊ธฐ ์œ„ํ•œ ์ž๊ธฐ์ผ์น˜ ์ถ”์ •๋Ÿ‰์„ ์ œ์‹œํ•œ๋‹ค. ๋…ผ๋ฌธ์˜ ๋‘ ๋ฒˆ์งธ์™€ ์„ธ ๋ฒˆ์งธ ๋ถ€๋ถ„์—์„œ๋Š” ๊ตฌ๊ฐ„์ž๋ฃŒ๋กœ ์ด๋ฃจ์–ด์ง„ ๋‘ ๊ฐœ์˜ ํ‘œ๋ณธ์„ ๋น„๊ตํ•˜๋Š” ๋ฐฉ๋ฒ•์„ ๋…ผ์˜ํ•œ๋‹ค. ๋จผ์ € ๋‘ ํ‘œ๋ณธ์ด ๋™์ผํ•œ ๋ถ„ํฌ์—์„œ ์ƒ์„ฑ๋œ ๊ฒƒ์ธ์ง€ ๊ฒ€์ •ํ•˜๊ธฐ ์œ„ํ•˜์—ฌ ์•ž์„œ ์†Œ๊ฐœ๋œ marginalization์„ ๊ธฐ๋ฐ˜์œผ๋กœ ํ•˜๋Š” ์ƒˆ๋กœ์šด ๋ฐฉ๋ฒ•์„ ์ œ์‹œํ•œ๋‹ค. ๋˜ํ•œ, ๊ตฌ๊ฐ„์ž๋ฃŒ๋ฅผ ๊ฐ–๋Š” ์„œ๋กœ ๋‹ค๋ฅธ ๋‘ ๋ชจ์ง‘๋‹จ์˜ ํ™•๋ฅ ์  ์ˆœ์„œ๋ฅผ ๊ฒ€์ •ํ•˜๊ธฐ ์œ„ํ•ด U-ํ†ต๊ณ„๋Ÿ‰์— ํ•ด๋‹นํ•˜๋Š” ์ƒˆ๋กœ์šด ๊ฒ€์ • ํ†ต๊ณ„๋Ÿ‰์„ ์ œ์‹œํ•˜๊ณ  ๋™ ํ†ต๊ณ„๋Ÿ‰์˜ ๊ท€๋ฌด๊ฐ€์„ค ํ•˜์—์„œ์˜ ์ ๊ทผ ๋ถ„ํฌ๋ฅผ ๋„์ถœํ•œ๋‹ค. ๋ณธ ๋…ผ๋ฌธ์—์„œ ์ƒˆ๋กญ๊ฒŒ ์ œ์•ˆํ•œ ๋ฐฉ๋ฒ•๋ก ์˜ ํŠน์„ฑ์„ ์‚ดํŽด๋ณด๊ณ  ๊ทธ ์„ฑ๋Šฅ์„ ํ‰๊ฐ€ํ•˜๊ธฐ ์œ„ํ•˜์—ฌ ๋‹ค์–‘ํ•œ ์ƒํ™ฉ์—์„œ์˜ ๊ฐ€์ƒ ๋ฐ์ดํ„ฐ์™€ ์‹ค์ œ ๋ฐ์ดํ„ฐ๋ฅผ ํ™œ์šฉํ•˜์—ฌ ๊ธฐ์กด ๋ฐฉ๋ฒ•๋ก ๊ณผ์˜ ๋น„๊ต, ๋ถ„์„์„ ์‹œํ–‰ํ•˜์˜€๋‹ค. ์ด๋ฅผ ํ†ตํ•ด ๋ณธ ๋…ผ๋ฌธ์—์„œ ์ œ์•ˆํ•œ ๋ฐฉ๋ฒ•๋ก ์ด ๊ตฌ๊ฐ„์ž๋ฃŒ์— ๋Œ€ํ•œ ๋ถ„์„๊ณผ ์ถ”๋ก ์— ์žˆ์–ด ์œ ์šฉํ•œ ํ•ด๋ฒ•์„ ์ œ๊ณตํ•˜๊ณ  ์žˆ์Œ์„ ํ™•์ธํ•˜์˜€๋‹ค.1.
