Feldblum/Brosius - Old All-10 questions

[Five in Two]

Comparing the TIA videos to the type of questions asked in All-10 (early-mid 1990's questions) there seems to be a different focus.

For instance, the 1993 #29 question asks:

Based on Brown's paper "Minimum Bias with Generalized Linear Models," what would Bailey's recursive formulas be, if the model were the combined additive-multiplicative function of (xi)(yi)+(zi)? How could this be solved?

I understand that the Feldblum/Brosius paper is new to the syllabus as of 2005, so there aren't many historical test questions, but I'm curious to see what I should focus on and when it's "safe" to move to the next paper. At current preparation level, there's no way I'd be able to answer the question above. If I have a grasp on the balance principle (multiplicative and additive), chi-square and squared bias error function, maximum likelihood from a theoretical perspective if not actually working with the formulas, then do you think it's safe to move on? If not, then what are you studying in addition to the above "simple" calculations?

After taking a look at the 2006/2007 problems, this paper is worrying me much less and the old exam questions seem to be obsolete.

Two balance principle questions. I'm guessing it's going to be a minimize sum of squared errors problem this time around.
