individual covariates

[annaren]

Really sorry to post another question but I am having problems using individual covariates in my model. I have used habitat size as covariate as I am interested to see the effect of habitat size on survival as I hypothesise that those in small, narrow habitats have a lower survival.
When I look at the parameter estimates the following message is given at the top:

Following estimates based on unstandardized individual covariate values:
Variable Value
--------- -------------
VAR1 7.2390948

Does this mean that MARK simply is taking an average of the covaraites to give the estimates and is there a way to make it use all values in order to answer my question,i.e. does survival increase as margin width increases?

First, parameter estimate - beta, or normal probability scale?

Second, what MARK reports (how, why, what you can change) in terms of parameter estimates for individual covariates, is covered in a fair bit of detail in current Chapter 11. If you haven't had a good look, take some time to read the chapter. If you have, start re-reading about midpoint on p. 12. Also, make sure you read section 11.5, which deals with visualizing the relationship between the parameter of interest and the covariate(s).
