Dear all,
I need to assign new observations to cluster groups previously identified for a
different dataset. The original clustering was performed using Clara. I gess
one way is to assign each new observation to the nearest medioid of the
original cluster. Is there a way of doing this in R? Is
Dear all,
Thanks for the responses to this post.
I understand that the topic still requires more research. However, I am a non-statistician in a
desperate need to analyze my ecological data with the currently available tools. Please excuse
again my non-expert question: Would I commit a huge
Dear all,
I want to evaluate several generalized linear mixed models, including the null
model, and select the best approximating one. I have tried glmmPQL (MASS
library) and GLMM (lme4) to fit the models. Both result in similar parameter
estimates but fairly different likelihood estimates.
My
Dear All,
I need to calculate the optimal number of clusters for a classification based
on a large number of observations (tens of thousands).
Thibshirani et al. proposed the gap statistic for this purpose. I tried the
R-code developed by R. Jörnsten but R hangs with such amount of data ().
