I am doing survival analysis similar to 'Muthén, B. & Masyn, K. (2001). Discrete-time survival mixture analysis. (#92)'. This works if I try to explain survival with observed independent variables. However, if I include a latent independent variable I get an error message: *** ERROR The following MODEL statements are ignored: * Statements in the OVERALL class: F ON E * Statements in Class 1: F ON E F is survival and E is a latent independent variable to explain survival chance. Is it possible to use latent independent variables in survival analysis (in Mplus 2.12)? |

You need Version 3 for this. |

I am conducting survival analysis using latent intercept and slope as predictors of mortality. Everything looks fine except that when I look at the unstandardized values one of the vars' significance is .08 and when I look at the standardized value the significance is < .01. Do you know why this is happening and what results I should trust? |

Dear Linda I have a question about the latent factor score in the Cox model with continuous a latent factor-- What is the estimated latent factor score based on? Is it related to the correlations or Eigen values? Thanks in advance! Best, Nan |

See Technical Appendix 11 for information on how Mplus estimates factor scores. That being said, I would not use factor scores as covariates in a Cox regression. I would define the factors in the MODEL command using the BY option and use these factors as covariates. |

Hi ! I am estimating a Cox regression model with some covariates. Is it possible to save the estimated survival (or hazard) function in Mplus Version 5/6 ? Thanks for your help! |
|
|
You can use the RESULTS option of SAVEDATA to save model results. The gph option created by the PLOT command contains all values that are plotted. |

Hello! I have a question concerning cox regression analysis in Mplus. Can you tell me how the different standardized results are calculated and how they can be interpreted? Thanks in advance. |
|
|
The are described generally under the STANDARDIZED option in the user's guide. See also Technical Appendix 3 on the website. |

I found the description and see how the parameters are calculated. Now I can interpretate the parameter estimates as the change in y in sd for a sd change in x. For this I am using the variance of the survival time, which is given in the Tech4 output. I was wondering if you can give me a reference on how this variance is calculated ? Thanks again! |

You can standardize a Cox regression coefficient with respect to x only. |
