stochprof.results.LNLN: Evaluation of results from estimation of LN-LN model

Description Usage Arguments Value Author(s) References

View source: R/stochprof.results.LNLN.R

Description

Evaluates the set of results that are passed to this function. That means, it removes entries where the target function is equal to infinity, it removes double entries, it removes unlikely parameter combinations (if there are too many) etc., and it sorts the data. When show.plots==T, the results are graphically displayed.

Usage

2
stochprof.results.LNLN(prev.result, TY, show.plots = T, plot.title = "",
   pdf.file, fix.mu = F)

Arguments

prev.result

contains parameter combinations and the respective value of the target function. It is typically the output of 'stochprof.search.LNLN'.

TY

number of types of cells assumed in the model

show.plots

if TRUE, the results are plotted. In particular, one plot is produced for each parameter, with the value of the parameter plotted against the value of the target function. This is not exactly the profile log-likelihood function because there is no conditioning on the other parameters being equal to the ML estimate. If the estimation procedure has converged, however, one can recognize the shape of the profile log-likelihood from these plots. A red bar indicates the position of the maximum likelihood estimator.

plot.title

title of each plot if show.plots==T

pdf.file

plots will be written into this file when this argument is not missing. The file has to include the entire path.

fix.mu

if TRUE, the log-mean of the lognormal distributions has been kept fixed. In that case, no plots will be produced for these parameters.

Value

Matrix with sorted and evaluated results. The columns are exactly the same as those in 'prev.result'. The first row contains the best estimate.
