toycluster.LNLN | R Documentation |
A matrix containing synthetic measurements from the stochastic profiling LN-LN model. There is data for 12 genes (columns) and 16 tissue samples (rows). Each measurement is the sum of 10 i.i.d. random variables from a mixture of lognormal distributions.
data(toycluster.LNLN)
The format is: num [1:16, 1:12] 0.789 4.698 4.643 8.734 12.458 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:16] "V1" "V2" "V3" "V4" ... ..$ : chr [1:12] "gene 1" "gene 2" "gene 3" "gene 4" ...
The true underlying parameters are:
TY = 2, i.e. there are two types of cells
p = (0.225, 0.775), that is the probability for cell type I and II, respectively
mu1 = (1.8853, 2.2758, 0.4748, 0.2658, 1.5745, 2.3938, 1.7389, 2.2148, 0.2104, 2.1032, 0.0638, 1.8109), that is the log-mean for cell type I for genes 1 to 12
mu2 = (-2.6637, -0.6590, -1.6308, -2.0753, -1.5786, -0.8131, -2.4872, -3.4486, -3.4865, -2.1848, -1.3868, -2.8238), that is the log-mean for cell type II for genes 1 to 12
sigma = 0.225, that is the log-standard deviation for both cell types
