In CenterForStatistics-UGent/combi: Compositional omics model based visual integration

Estimate a column-wise mean-variance trend

Description

Estimate a column-wise mean-variance trend

Usage

estMeanVarTrend(
  data,
  meanMat,
  baseAbundances,
  libSizes,
  plot = FALSE,
  meanVarFit,
  degree = 2L,
  constraint = "none",
  ...
)

Arguments

data	the data matrix with n rows
meanMat	the estimated mean matrix
baseAbundances	The baseline abundances
libSizes	Library sizes
plot	A boolean, should the trend be plotted?
meanVarFit	A character string describing the type of trend to be fitted: either "spline" or "cubic"
degree	The degree of the spline
constraint	Constraint to the spline
...	additional arguments passed on to the plot() function

Value

A list with components

meanVarTrend	An smoothed trend function, that can map a mean on a variance
meanVarTrendDeriv	A derivative function of this
