我研究生课程学这部分的时候是有1/2，对于LEVEL1 里面没有1/2感到很奇怪。然后翻了下课程课件，发现教授在某一页下面注释里写着Sometimes see effective convexity reported as half this amount (building in the factor of ½
from the formula on the previous page for P taking into account convexity ).
我想大概是有1/2更精确吧

找到一点：LOS 58.i上方有句话说这个了，often the measure is calculated in a way that requires an analyst to divide the measure by two to get the correct convexity adjustment. 我想这就是effective convexity

看了2014年版的notes，LOS 55 k 明确写了有1/2的
