## Simulate Kersplat gene means

### Description

Simulate Kersplat gene means

### Usage

    kersplatSimGeneMeans(params, verbose)

### Arguments

`params` | KersplatParams object containing simulation parameters.
`verbose` | logical. Whether to print progress messages

### Details

Gene means are simulated in one of two ways depending on the value of the `mean.method` parameter.

If `mean.method` is "fit" (default) then means are sampled from a Gamma distribution with shape equals `mean.shape` and rate equals `mean.rate`. Expression outliers are then added by replacing some values with the median multiplied by a factor from a log-normal distribution. This is the same process used for the Splat simulation.

If `mean.method` is "density" then means are sampled from the density object in the `mean.density` parameter using a rejection sampling method. This approach is more flexible but may violate some statistical assumptions.

### Value

KersplatParams object with gene means
