估错

The team checked Pagulayan's video records and found that people were firing at the aliens when they were too far away, misjudging the range of the weapon and wasting bullets.

团队检视了Pagulayan的视频录像，才发现玩家往往在敌人还很遥远的时候就开枪射击，错估了武器的火力范围，所以浪费了弹药。

We should point out again that in any given year a company writing long-tail insurance (coverages giving rise to claims that are often settled many years after the loss-causing event takes place) can report almost any earnings that the CEO desires. Too often the industry has reported wildly inaccurate figures by misstating liabilities. Most of the mistakes have been innocent. Sometimes, however, they have been intentional, their object being to fool investors and regulators. Auditors and actuaries have usually failed to prevent both varieties of misstatement.

我们必须再一次指出，一个签发长尾型保险的公司(保单理赔范围通常在损失事件发生好几年后才会理赔的保单)，其经理几乎可以随心所欲的操控其短期的盈余数字，这行业因为负债错估而导致报表数字不真实可说是司空见惯的事，大部分的错误或许都是出于无心，但有时也有可能是故意的，其目的无非是想要误导投资人以及主管机关，而会计师以及精算师往往无法预防此类的事件发生。

First make the subjects give either right or wrong responses to the same question with different b value. When estimating the abilities of the subjects with the use of one-parameter or two-parameter Logistic model, it is found that there exists two kinds of unfits.(2) Estimate the abilities of the subjects after introducing c parameter on the basis of the two-parameter model. The first unfit can be rectified. However, the second unfit still exists and the third unfit appears.(3) Then estimate again after introducing y parameter. It is discovered that the second unfit is rectified, but the first unfit still exists and the fourth unfit appears.(4) Form Logistic four-parameter model by introducing c parameter and y parameter at the same time and estimate one more time. This model makes all kinds of unfits, including the first, second, third and fourth unfits, rectified.

1设计这批被试分别做对或做错一道b值不同的试题，用Logistic单、双参数模型对被试进行能力估计时，发现被试能力估计存在着两类失拟现象；(2)在双参数模型基础上增加c参数，对被试进行能力估计，发现c参数能有效纠正第一失拟现象，然而仍然存在第二失拟现象，同时还存在第三失拟现象；(3)在双参数模型基础上增加γ参数，再对被试进行能力估计，发现γ参数能有效纠正第二失拟现象，而仍然存在第一失拟现象，同时还存在第四失拟现象；(4)同时增加c、γ参数形成Logistic四参数模型，再对被试进行能力估计，这时该模型对各类失拟现象，包括第一、第二、第三、第四失拟现象都具有良好拟合能力。
