makeModel: Generate a design matrix corresponding to the 2-1-0 hurdle

In amcdavid/HurdleNormal: 'Estimation and sampling for multi-dimensional Hurdle models on a Normal density with applications to single-cell co-expression'

Generate a design matrix corresponding to the 2-1-0 hurdle

Description

Generate a design matrix corresponding to the 2-1-0 hurdle

Usage

makeModel(
  zif,
  nodeId,
  fixed = NULL,
  center = TRUE,
  scale = FALSE,
  conditionalCenter = TRUE,
  tol = 0.001
)

Arguments

zif	zero-inflated covariates
nodeId	names to be used for nodes. 'colnames' of 'zif' will be used if provided.
fixed	optional matrix of fixed predictors
center	center design matrix
scale	scale design matrix
conditionalCenter	in positive predictors, center only the non-zero components (design matrix will still be centered, and orthogonal to indicators)
tol	tolerance for declaring a parameter equal to zero

Value

design matrix, with attribute fixedCols giving indices of unpenalized intercept columns. Each gene appears in adjacent columns with its continuous component first, followed by its binarization.
