S4 class that holds parameters for the simple simulation.
Parameters
The simple simulation uses the following parameters:
nGenesThe number of genes to simulate.
nCellsThe number of cells to simulate.
[seed]Seed to use for generating random numbers.
mean.shapeThe shape parameter for the mean gamma distribution.
mean.rateThe rate parameter for the mean gamma distribution.
[count.disp]The dispersion parameter for the counts negative binomial distribution.
The parameters not shown in brackets can be estimated from real data using
simpleEstimate. For details of the simple simulation
see simpleSimulate.
