Separate names with a comma.
The question talks about setting claim reserves on outstanding claims... I am slightly unclear on how this works in practice. I was under the...
Hello, I am struggling to see how the free assets in 2003 has come to 396. In my calculation I have assets = bonds (1b) + DAC(0.66) / liabs =...
Broadly speaking, given that IBNR in reporting year only consists of IBNER, in accident year it consists of pure IBNR & IBNER, and underwriting...
I can follow the calculation of mu and sigma, but where are the mean of A & B coming from?
I am struggling to get my head round the inflation trending in this calculation. In the aset solution an index is created whereby we trend product...
In calculation of the profit and loss, of the QS contracts, is it the market accepted way to calculate profit commission as PC% * ceded premium ?...
Haha apologies - september 2007 !
sorry says in the title - st3 q2ii
I am not following the rationale in the answer for the average accident date in 06' - would someone be able to explain? Thanks Ed
Why is the effect of b less apparent at older ages? Intuitively I would have thought time would have a greater effect on death at older age
Why is the correct test statistic here (A-E)^2 / E, rather than z?
Great - thanks Dave - I was losing a sigma^2 when taking the covariance of the (yt-1,et-1)
Thanks Dave... Are you not using E(X^2) instead of V(X)? I would have thought to use the V(X)=200 given in the question
For part (c), given that we are dealing with a compound poisson distribution, I have calculated the variance = lambda*E(X^2) where lambda = 0.3...
On this question, I can see that for Model X, we can derive an estimate for a1 by calculating: Autocov(0)=Cov(a0+a1yt-1+et,yt) = a1*autocov(1) +...
Got you - thanks for your help Dave
What is it exactly that makes the Cox PH semi-parametric? Does the parametric come from the fact that the baseline hazard has an exponential shape?
How is the equation for the variance of S derived in this question. I cant see where we are losing one of the terms in the compound variance equation?
In the core reading it states that a process with independent increments has the markov property. However, independent increments is independent...
May be my lack of understanding but... why should we think to difference the equation to solve for a and sigma?
Thanks Dave!
Thanks Dave ! One more question... On part (iv), when calculating PHR, why has it been decided to calculate via integrated equations. Would it be...
Hello, What are the possible documents that we could be required to write? At the moment I have only seen a letter / report or memo in past...
Hello, In an MA(q) process where q>=1, the PACF tends to 0 but never completely cuts off... Likewise, for an AR(p) process where p>=1, would we...
What does the questions mean by the nature of the boundaries? The answer suggests a 'mixed type', which implies the process operates in continuous...
Why do we not consider sickness a holding state? Is it due to the short time period (an hour) that we are there for?
Part (iii), why are we differentiating and hence minimising the gradient with respect to Xa ? Is this the line that provides the highest expected...
