Hi,
Does heatmap.2 function combine all variables into a single overall measure of
dissimilarity (regardless of dissimilarity) between two observations as
explained in The elements of statistical learning, Hastie et al, 2001, pp457?
Does this function calculate the dissimilarity between observations and
variables as follows?
N N p
1/(N^2) sum sum sum d(xij,xi'j)
i=1 i'=1 j=1
where N is the number of observations, p the number of variables, xi and xi'
are two different observations, and d is the dissimilarity between two
variables, respectively.
Any relevant information is welcome.
Best,
Carol
