I want to perform a multiple regression in R and make predictions based on
the trained model. Below is an example code I am using:
price = c(10,18,18,11,17)
predictors = cbind(c(5,6,3,4,5),c(2,1,8,5,6))
predict(lm(price ~ predictors), data.frame(predictors=matrix(c(3,5),nrow=1)))
So, based on th
Hi,
I am trying to use GotoBLAS2 on R 3.0 on Unix. I downloaded GotoBLAS2
source code from TACC web site, compiled it, and replaced libRblas.so with
libgoto2.so, following the instructions at the link
http://www.rochester.edu/college/gradstudents/jolmsted/files/computing/BLAS.pdf.
The simple matri
Hi,
I want to cluster my data points into K clusters using k-means algorithm,
and I want to use a deterministic (non-random) initialization scheme which
is also a "good" start. I found a paper by Ting Su and Jennifer Dy named "A
Deterministic Method for Initializing K-means Clustering" and I wonde

Hi,
Does anybody know the difference between the Lloyd and Forgy algorithms
specified for R's kmeans clustering options? I know how Lloyd works, but I
cannot access Forgy's paper and could not find any specific information on
the web about how it really differs from Lloyd's method.
I appreciate y
