Chapter 974 - 910: It Makes Sense
Wang Chuanxing made a photocopy of Jiang Yuan’s paper on the estimated age at death and distributed it to several experts for review.
Professors Sun, Li, and Zhang drew on the paper, divided it into three sections, and then each set up their own workstations to verify the findings.
They were very familiar and accustomed to reviewing the work of others and providing evaluations.
Despite this, the three were very cautious and careful.
Estimating the age at death is a very difficult and valuable academic problem. Moreover, the estimation of age at death is closely related to the development and application of science and technology.
In other words, it is normal to make mistakes, and even more normal for discrepancies to occur.
To reduce errors and avoid mistakes, everyone naturally uses various methods and tries different schemes. A typical approach, for example, is using a more fitting regression equation.
Regression equations are not secret martial art techniques; they are more of statistical results, and are generally public—yet, they are somewhat like martial art techniques since scholars might keep effective regression equations to themselves for personal use. Especially today, with the increase in horizontal commercial projects, even if scholars want to publicize newly developed regression equations, commercial companies might not be pleased.
On the other hand, the most important part of regression equations is not the equations themselves, but the prerequisites; that is, under what conditions which regression equations should be used.
This aspect is also very much like martial art techniques. The same regression equation might be very suitable for Caucasians, or even more specifically for the Caucasian race, and if you use it for the Mongoloid race, assessing its effectiveness, whether adjustments are needed, or if a coefficient should be added and where, then it becomes a matter of great complexity and similar to secret martial art techniques.
