...R optim. No problem! But now I want to include a covariate indicating a time-varying value at each failure time t. For constant covariates, the procedure is feasible : leads to following log likelihood funciton: here zi are the covariates which are constant for each unit i under observation. tij are the failure time for failure j of unit i. Do you know how to formulate a log likelihood function for covariates which vary for each tj of each unit i ? Thank you very much Best regards Martin Wagner Berlin University of Technology

I'd really like to receive mail again, especially now that the NNTP service is down. Thanks in advance, -- Tijs van Bakel, ConnecTUX, <tijs@connectux.com>

...for Office, _don't_ install Internet Explorer 5.0, but only the minimal component. Also, the installer only worked when _not_ using Desktop mode. Unfortunately, Office 2000 doesn't work flawlessly for me. I seem to be unable to save documents in Word, for instance. Hope this helps, -- Tijs van Bakel, ConnecTUX, <tijs@connectux.com>

Hi, I have a linear mixed-effects model object and want to extract the 95% confidence intervals for the fixed and random effects, respectively. I found the function intervals() for confidence intervals for the fixed effects but no corresponding function for the random effects. Does it exist or do I have to calculate the confidence intervals for the random effects myself? Greetings, joerg
