To determine the rank of regression coefficient matrix in a multivariate linear regression model, a model selection procedure is proposed based on the M-estimation.

为了确定多重线性回归模型中回归系数矩阵的秩，本文提出了一个基于M估计的模型选择程序，且在较弱的条件下建立了回归系数矩阵的秩的估计的强相合性。

A new method for estimating fish natural mortality coefficient (m), based on the extended survivors method, using a catch-at-age data and an abundant index (catch per unit effort, CPUE) was proposed.

基于扩展残存资源量法，提出一种根据分年龄组渔获量以及资源量指数(单位捕捞努力量渔获量，CPUE)求算鱼类的自然死亡系数(M)的新方法。

And so instead of defining efficiency the way you've got it written there, I'm going to define what's called something different for a refrigerator which is called the coefficient of performance.

现在我们不用,效率的那个定义，我给出一个,有关制冷机的,新的定义,叫做制冷系数。
