Hello,
I am conducting a latent profile analysis in mplus and for that I need to determine the starts (LRTSTARTS, LRTBOOTSTRAP etc.). I have found an article explaining it, but I can't make sense of it.
"(...) STARTS = 1000 250;
STITERATIONS = 500;
! Default number of starts for each step of the ML estimation. First STARTS value specifies the !number of unique start values to start with, the 250 represents the 250 best unique start values !carrying forward to completion. The STITERATIONS specifies the number of ML iteration
!steps for those 250 selected start values to go through to be able to converge. This is a
!maximum number of iteration; if a model converges in less than 500 iterations it will stop
!before reaching 500 iterations.
!These values can be increased … see “Four-Profile Final Model with Covariate Analysis
!Syntax” for an example.
LRTSTARTS = 2 1 50 10;
LRTBOOSTRAP = 250 (...)" (from Ferguson et al., 2020)
Can somebody help me by explaning it in 'normal' words?
Kind regards,
Indra
Dear Indra Dv
I recommend you consult the manual that appears in the following link https://www.amazon.es/Structural-Equation-Modeling-Applications-Probability/dp/1119422701
