Hi there,
I was trying to fit this dataset into LR model. This dataset includes 18 normal
and 17
cancer. There are totally 14 markers (7 mRNAs and 7 Proteins). When I fitted
into LR
model, R gave me warning:
Warning messages:
1: algorithm did not converge in: glm.fit(x = X, y = Y, weights = weights,
start = start,
etastart = etastart,
2: fitted probabilities numerically 0 or 1 occurred in: glm.fit(x = X, y = Y,
weights =
weights, start = start, etastart = etastart,
I don't know why the algorithm did not converge. Is it because sample
size/marker is
small? Is it possible you run this dataset in s-plus? Thank you very much for
your help.
Michael
