hypoData_ts: A sample microarray data for detecting tissue-specific patterns.
Description
A hypothetical micoarray data consisting of eight rows (genes) and ten
columns (tissues). The expression patterns are quite similar to those
in figure 1 in Kadota et al., 2006.
Format
hypoData_ts
is a matrix of dimension eight times ten.Details
The hypoData_ts
is designed for explaining the performance of
ROKU
that identify tissue-specific expression patterns.
The hypoData_ts
contains a total of eight genes having various
expression patterns across ten tissues: (1) 'up-type' genes selectively
over-expressed in a small number of tissues but unexpressed ("gene1"),
slightly expressed ("gene3"), and moderately expressed ("gene4"),
(2) 'down-type' genes selectively under-expressed ("gene5"),
and (3) 'mixed-type' genes selectively over- and under-expressed in
some tissues ("gene6"). The other genes are not tissue-specific genes
(i.e., "gene2", "gene7", and "gene8").
