[R-sig-ME] interpretation variance-covariance estimates with gaussian and censored exponential

[Van Dongen Stefan]

Hi All,

I am currently running a multivariate animal model which has 3 normally distributed responses and one time-to-event (longevity) response. For the fixed effects part, the estimated slopes for associations with longevity reflects changes or ratio's in hazards (i.e., positive estimate = shorter longevity), but how should I interpret the covariances/correlations in the variance covariance matrices (genetic and environmental)? Correlations with hazards or survival-times?

many thanks

Stefan
