Update W and P in EMFA algorithm

Description

Update W and P used in the iteration process in the EMFA algorithm.

Usage

updateFA(
  y,
  wStart,
  pStart,
  wNew,
  pNew,
  m0,
  hetVar = FALSE,
  maxDiag = 10000,
  tolerance = 1e-04,
  maxIter = 100L,
  printProgress = FALSE
)

Arguments

y	An n x p matrix or data.frame.
wStart	A p x p matrix or data.frame containing starting values for W.
pStart	A p x p matrix or data.frame containing starting values for P.
m0	An integer. The order of the model.
hetVar	Should an extra diagonal part be added in the model for the precision matrix?
maxDiag	A numerical value for the maximum value of the diagonal of P.
tolerance	A numerical value. The iterating process stops if the sum of the difference for P and W between two steps gets lower than this value.
maxIter	A numerical value for the maximum number of iterations.
printProgress	Should progress be printed during iterations?
