fmx2dbl function

Reparameterization of fmx Object

To convert the parameters of fmx object into unrestricted parameters.

fmx2dbl(
  x,
  distname = x@distname,
  pars = x@pars,
  K = dim(pars)[1L],
  w = x@w,
  ...
)

Arguments

• x: fmx object
• distname: character scalar, default x@distname
• pars: numeric matrix , default x@pars
• K: integer scalar, default value from x
• w: numeric vector , default x@w
• ...: additional parameters, not currently used

Returns

Function fmx2dbl() returns a numeric vector .

Details

For the first parameter

• $A_1 \rightarrow A_1$
• $A_2 \rightarrow A_1 + \exp(\log(d_1))$
• $A_k \rightarrow A_1 + \exp(\log(d_1)) + \cdots + \exp(\log(d_{k-1}))$

For mixing proportions to multinomial logits.

For 'norm': sd -> log(sd)

for 'GH': B -> log(B), h -> log(h)
