Afline adjustment of a bi-varied protocol with calculation of the linear regression and the
coefficient of correlation.
Linear regression of y into x:
Y___a.X+b=,
a = X — rnxY — my = CavarianceX,Y
“X _ mxflz Variam:eX
b = my —a -mx
Quality of the adjustment
rX,Y = cosX —mxY — my
CavX, Y
Z JVarx> -JVarY>
rX, Y = 2 1 perfect adjustment
rX, Y = 0 bad adjustment
The general coeficients at correlation are as follows:
Karimarra 0.09 bad generalised category
Purungu 0.32 bad generalised category
Panaka 0.44 bad generalised category
Paljeri — 0.66 average generalised category but to a lesser degree than previous cats.
Burgulu - 0.71 relatively good dislocated category
Tjarurru 0.03 bad localised category
Milangka 0.88 relatively good localised category
Yiparrka0.02 bad localised category
