initial_value: inital value for flash

In kkdey/flashr: Factor Loading Adaptive SHrinkage in R

Description

description inital value for flash

Usage

initial_value(Y, nonnegative = FALSE, factor_value = NA,
  fix_factor = FALSE, fl_list = list())

Arguments

Y	the data matrix
nonnegative	if the facotor and loading are nonnegative or not. TRUE for nonnegative FALSE for no constraint
factor_value	is the factor value if the factor is fixed
fix_factor	whether the factor is fixed or not TRUE for fix_factor FALSE for non-constraint

Value

list of factor, loading and variance of noise matrix

• El is a N vector for mean of loadings

• El2 is a N vector for second moment of loadings

• Ef is a N vector for mean of factors

• Ef2 is a N vector for second moment of factors

• sigmae2_vis a N by P matrix for residual square

• sigmae2_trueis a N by P matrix for estimated value for the variance structure
