-BF methods take expected emergence in each period to be a percentage of ultimate losses
-Cape Cod and additive chain-ladder models assume that years showing low losses or high losses to date will have the same expected future dollar development (because they assume a constant h over all years)
you could read page 826 of Venter, you could also use the excel file for Venter to try and reproduce the result from the paper found at this link https://risingfellow.com/resources

There’s no graph of residuals over time (from Implication 4) in Venter but I could see that being tested and want to make sure I’m thinking about it correctly. Would that look the same as the graph of residuals against losses, but the x axis would be AY? So basically, we would basically be reordering the residuals from sorting by loss size to sorting by AY.

yea I'd imagine. you could probably have a calculation question where you get residuals manually and then they test if you recognise that implication

Just found out that the source material of Brehm is not available online. Is CF/CR seminar possibly sufficient for that section?

not really, it's just jot note form and lacks a lot of the context you get from reading the source

Quick question... Is there a way to store/copy output from 1/2-Var Stats on a TI-30XS Multiview? I always find myself writing down the output, just to type it into my calculator again. Thanks.

Selecting a variable and hitting enter inserts it into whatever equation you are currently working on.

What about to get it to the home screen?

You can clear the formula and then use a new column.
