MODELMAPS Gets polynomial models from data interactively
CALLS
[Pol,Str,planes] = modelmaps(p,C,som,vars)
p: data matrix (RxQ)
C: Covariance value (scalar)
som: SOM structure
vars: indices of two variables to be analyzed
Pol: Cell array containing vectors of polynomial coefficients
for each polynomial model P(x)
Str: Cell array containing strings with the polynomial model (meant for
titles)
planes: Residual planes corresponding to evaluation of res = y-P(x)
Description
MODELMAPS allows to obtain polynomial models between two variables in
an easy way by clicking points in a scatter plot. The validity of the
obtained models can be assessed later over the SOM model by evaluating
the residuals y-P(x) for variables x and y of the SOM codebooks. This
is automatically done in the variable planes.
