Ratio estimate

Japanese: 比推定 - ひすいてい(英語表記)ratio estimate
Ratio estimate
One of the estimation methods used in mathematical statistics. Suppose there are N jars, each containing a different amount and concentration of salt water. Number the jars and let the amount of salt water in the k -th jar be x k and the amount of salt it contains be y k . In this case, there are two types of measurements: x 1 , x 2 , …, x N y 1 , y 2 , …, y N. Assume that N is a very large number, and that it is possible to inspect the salt water in the first n jars ( n < N ). In other words, x 1 , x 2 , …, x n ; y 1 , y 2 , …, y n can be known.

数理統計学で用いられる推定法の一つ。N個の壺があり,それぞれの壺の中に量,濃度の異なる食塩水が入っているとしよう。壺に番号をつけk番目の壺に入っている食塩水の量をxk,その食塩水が含む食塩の量をykとする。このとき2種類の計量, x1,x2,……,xN y1,y2,……,yNが存在することになる。Nは非常に大きな数であるとし,最初のn個(nN)の壺の食塩水について検査できるとする。すなわち,x1,x2,……,xny1,y2,……,ynは知ることができる。
