Estimation of Product Claim Rate with Consumer's Inspection Error

소비자(消費者) 검사오류(檢査誤謬)를 고려한 제품(製品)의 반환율(返還率) 추정(推定)에 관한 연구(硏究)

In claiming for the purchased products, two types of errors can occur from the consumer's point of view. One is to accept defective products and the other one is to reject good products. Due to such errors, Claim rate for the products is expected to be different from that the producer has originally anticipated. In this paper, the probability distribution of the number of claimed products when such consumer's inspection errors are involved is derived. Then, a simple model is provided to estimate the claim rate when such errors are present.
