kWayStratifiedYReplace | R Documentation |
Build a k-fold cross validation sample where training sets are the same size as the original data, and built by sampling disjoint from test/application sets (sampled with replacement).
kWayStratifiedYReplace(nRows, nSplits, dframe, y)
nRows |
number of rows to split (>1) |
nSplits |
number of groups to split into (<nRows,>1). |
dframe |
original data frame (ignored). |
y |
numeric outcome variable try to have equidistributed in each split. |
split plan
set.seed(23255)
d <- data.frame(y=sin(1:100))
pStrat <- kWayStratifiedYReplace(nrow(d),5,d,d$y)
