standard error for the estimated value (lmer fitted model)
...n using lmer. I have two predictors: cafr and
its quadratic form I(cafr^2), where cafr is a variable centered around the
mean of original variable. Now, the estimated value from the fitted model
will be,
(model@X)%*%fixef(model)
In the logit scale, the mean sum of square from fitted model will be,
sesample=sqrt(sum(resid(model)^2)/(n-p-1)), where p is the degrees of
freedom used for fitting.
Could someone make a judgement if it is reasonable to calculate standard
error of the estimated value by
sesample*sqrt(vector%*%ginv(t(model@X)%*%model@X)%*%t(vector))
, where vector is the (1,cafr,I(cafr^2)) whi...

RSpec
Hi RSpec Mailing list,
I''m new to RSpec and I am trying to get it running with the caboo.se sample
rails app.
I installed the current version of rspec with rspec_on_rails
I tried to run rake spec but received:
