First it is important to note that studies focus on different grade levels, subjects, and types of students taught, and in some cases the estimated effects of particular attributes are not consistent across the board.

In this new work Quirk has looked at the effect right across the country and the years when the satellite estimates diverge from the ground thermometers are indeed the wetter years.

's 5 W / m2 is even close to accurate, in looking at some calculations I've seen, which show that the difference between the peak solar cycle and the minimum is about.322 W / m2 across the entire planet in terms of irradiance, and this translates into about.2 C in global temp difference on average, then my rough estimate of.1 C in TSI effect in 1998's El Nino versus 2009 - 2010 is an undershoot, but either way it looks like the TSI effect in 1998 is far more than the.01 C that some have suggested would be the level to be even significant.

if you've got a bivariate random parameters (intercepts and age effects) up and running, and so can estimate a correlation or covariance between initial growth rate (the tree - specific random additive effect at age = 1) and tree - specific random age coefficient across the sample, the significance of that correlation / covariance would be a first crack at this without choosing an age at which to split the sample.
