with this discussion in a structure much
simpler than that of Professor Paul Tillich, we shall attempt what he calls a «method of

correlations and skillfully adjust her diet accordingly.
Many researchers now believe that real advances in genomics will come not from
simple X-causes-Y
correlations but from a rich statistical understanding that emerges out of the sequences of millions of genomes — a set that reveals how our genetic code is likely to interact
with the environment to make us who we are.
Robert M. Yerkes and John D. Dodson - the two researchers behind the self - titled «Yerkes - Dodson law» — came up
with a
simple yet savvy way of explaining the
correlation between arousal and performance.
This
simple correlation is not corrected for unreliability of the measures of grit and Big Five traits (a measure that has a test - retest reliability of.80 can not correlate
with another measure at a higher level than.80 —
correlations can be corrected for this attenuation).
Not surprisingly, parent socioeconomic status is strongly predictive of student test scores, and, looking at
simple correlations, we find that less - advantaged students do tend to be assigned to teachers

The importance of
correlation in the investing world comes from the
simple (and Nobel Prize winning) insight that since investors naturally seek to minimize risk, what they should do is construct portfolios
with assets that have as low a
correlation with each other as possible.
Mispricing theory would argue that investors are unable to correctly translate information beyond
simple financial metrics into efficient prices, and risk theory would argue that several metrics related to quality are associated
with a distinct undiversifiable
correlation pattern, which in a multifactor setting may signal that quality stocks are compensated by a risk premium.
While Hussman's formula is exceedingly
simple,
with a
correlation of more than 0.8 it's also highly predictive.
My only remaining skepticism had to do
with the use of this
simple correlation for predicting the future «to within a millikelvin»: namely, that the
correlation ignored two real constraints on future atmospheric CO2 increase, from human emissions upon which the entire
correlation is based.
A
simple combination of these three parameters that is [Td] n +2 − -LRB-[Ta] n + [Td] n − 3) is used and its
correlation with [E] n is computed for n = 10 — 21.
Simple calculation shows that this residual oscillating component (it very closely matches the AMO
with amplitude excursion of ~ 0.6 C) is directly related to the sunspot cycles for the period: http://www.vukcevic.talktalk.net/GSC1.htm On the other hand there is close
correlation between the N.A. SST (AMO) and global temperatures for period 1880 - 2010,
with a single exception at 1969 - 70 when there is an inexplicable drop in the AMO of 0.325 C, and than trends continue on a parallel up - slope.
Presumably industry and its CO2 production will correlate
with many things we are doing to the planet, so
simple correlation is not enough.
I would love to see CO2 plotted on top of the second graph
with the MWP so that my
simple brain could see the
correlation.
«The
correlation of changes in d13C
with ENSO events and the comparison
with a
simple model of a series of cascades suggest that the changes in d13C in the atmosphere have little to do
with the input of CO2 emissions from the continuous use of fossil fuels.»
With a PC link, the data can be used for all sorts of projects, from
simple averaging ones to looking at
correlations between different measurements such as wind direction and temperature.
But that's an entirely different issue from the very
simple one about Mann's
correlation of sediments from Finnish bridge building
with global climate fields — something that may qualify as a classic example of spurious
correlation, up
with Yule's original alcoholism and C of E marriages.
The regression F statistic (
with 1, n - 2 DOF) for a
simple correlation is (n - 2) * R2 / (1 - R2).
A
correlation of 0.999 suggests that there are no differences in the devices and that you would get almost precisely the same measure
with a
simple transformation of the raw data.
There has actually not been a rise in direct
correlation with simple marijuana use and car crashes.
This
simple correlation is not corrected for unreliability of the measures of grit and Big Five traits (a measure that has a test - retest reliability of.80 can not correlate
with another measure at a higher level than.80 —
correlations can be corrected for this attenuation).
