Is there a package in R which implements the weighted maximum likelihood method? I write it in R and Java. Can send you the code but it's ugly... Not a Newton Raphson but a "split half" search. |

An R function for performing searches for this purpose you can see the stringr package of H. Wickam |

When do you consider a variable is a latent variable? Thanks i see what you mean... But my goal is to have statistics rules. The complexity you talk about can be seen in econometrics problems which use classical approach. |

Classification after factor analysis Yes i think to cluster analysis rather than classifcation. |

Differences between tetrachoric and Pearson correlation Thanks for explanation and references. But what i would know is when values obtained from tetrachoric are slightly different of person coefficient. Because they're supposed to be close. Indeed, in many programs, for estimation, Pearson r are used as start values for algorithm which compute tetrachoric correlation. |

Differences between tetrachoric and Pearson correlation matrix is 5000 x 300. Software is SAS. PROC CORR and PLCORR. Convergence was not reached so the number of iterations have been changed to 100 iterations. |

Statistical inference when the sample “is” the population sorry. I have difficulties to understand how i would compute permutations and what conclusions I'll be able to made for them. |

Classification after factor analysis Thanks for your answer and reference. I will check differents models and do cross validation. Bayesian is a good idea. |
