原来的医疗保险已经过期了(11月中到期,不到一个礼拜).现在雇主给买的医疗保险到

保险心里很不踏实,但是问过的公司都说要申请一个月后才会生效,最快的也要到12月1

目前在看health reserving的东西，有点疑问。首先，health reserving和p&C
reserving很像，但又有不少区别。比如p&C reserving里会有reported（incurred)
loss, paid loss的区别,还会要考虑p/i ratio.比如比较新的munich chain ladder就
是可以缩小p/i ratio的一个方法；但是，在health里好像没有reported loss这个概念
，只有paid loss,然后自己算completion factor(就是1/LDF,财险里的reported %（好
像是啊）),然后用paid loss/CF算出来estimated incurred loss,也就是说人家都用不
上munich chain ladder这么有技术含量的东西。
再有个小疑问就是健康险里算completion factor我觉得又不太像1/ldf,好像是1/(LDF1
*LDF2*LDF3....LDFn),关键是ldf这里已经是cumulative loss的了，再乘起来就挺奇怪
的了。举个数字的例子吧：1,2,4,8,8,8,8,8,(cumulative loss啊）ldf就是，2，2，2
，1。。。。然后cummulative ldf就是，8，4，2，1....,1/ldf就是12.5%,25%,50%,
100%....Health insurance 里也是12.5%,25%,50%,100%....但是算completion factor
好像是把这几个数再乘起来，得到：0.015625,0.125,0.5,1....我觉着挺奇怪的，这事。

你的问题看的不是很明白啊 每一年的ratio算出来 最终的ratio当然需要全部乘起来
能不能在说的通俗点啊
ldf 应该是每一年的损失比率吧？ 就是说每一年比上年的损失比率的均值，最终的损失应该要吧因子乘起来
看你的描述应该是用的BF法则，先估计出最终的损失，然后再除以发展因子来估计未决赔款准备金吧。但是发展因子还是需要每年的乘起来，这个不会变的。

Pure luck I guess. I have two sites listed there. For one site, after 6
months of submission with no luck, I decide to apply to be the editor for
the category. I was approved and I added my site as well as 4 other

submission. It is pure luck. No trick. The sad truth is that DEMOZ is still
very very valuable for google search ranking. The traffic it can bring you

"关键是ldf这里已经是cumulative loss的了"?这句话怎么理解 没看懂
ldf全称是loss development factor
在triangle里面是通过当月的loss(either paid or incurred) 除以前月的loss
是一个ratio 怎么会是cumulative loss
关于你health insurance completion factor计算那段 很可能是你弄错了

incurred = paid + case reserve
when a claim is reported to the insurer, a claim number is assigned
to it, and depending on the nature of the claim, claim department
would set up a case reserve for that. at any time, the cumulative
paid amount + the case reserve = incurred.
on day 1, probably your paid is 0(since you rarely pay anything
right away), and your case is some non-zero value. as you have
more info regarding the claim, you would pay more and more(assuming
no negative paid), and your case reserve normally decrease(assuming
your initial estimate of the claim amount is fairly accurate).
after you have settled the claim, you close the claim by reducing
the case reserve to 0. now your paid = incurred, and this is also
you ultimate claim value. reserving is to estimate this value
periodically.
hope this helps.

In health, we don't say "reported loss". total incurred = paid + IBNR (
incurred but not reported) + reported but not paid. some actuary use
incurred = paid + IBNA (incurred by not adjudicated) + adjudicated but not
paid. Typically, you don't need a reserve for the "reported but not paid" as
the number should be known or close to be known. It is the IBNR or IBNA
that needs a reserve. We do use lag triangles and CFs to estimate INBR and I
agree with one of the posts that the method is same as what's used in P&C
except the rows and columns are switched.

Once a claim is filed, it should be recorded in the claims system right away
. However, depending on how complicated the claim is, it may some time to
adjudicate the claim, i.e. Determine whether the claim is eligible for
payout, how much the plan should pay, etc.. It also takes time to actually
cut the check and send it out.
