2. ### Ensuring test assumptions are met in a GLMM or GEE when using non-gaussian families

Hi all, I've been trying to test some of my data using either a GLMM or a GEE in R. When using a gaussian family with an identity link function, I can easily assess that the assumptions of normality and homoscedasticity are met by using a qqplot and Shapiro-Wilks test on the residuals for the...

6. ### invertible to positive absolute link

7. ### canonical parameter and canonical link function

Given the exponential distribution: f(x)= \theta^{-1}e^{-x/\theta. Converts it into exponential family form: exp[\frac{(1/\theta)x-log(1/\theta)}{-1}] Isn't the canonical parameter and link function the same? Which is \frac{1}{\theta} Are there any differences between canonical...
8. ### Chain link strength knowing the failure strength of several chains

I ran some materials tests earlier today, and this is the most basic way to describe my problem: I have n chains, each with x links on them. If I test each of the n chains to failure. Only the failure strength is recorded. How can I predict the mean failure strength of each chain link...

I found my way to this forum eventually but in the FAQ question regarding how to write mathXL or whatever Latex is using, there is a dead link to a thread supposedly explaining what Latex is and how to use it. I guess it should link to the first sticky post here or this Forum in general. Bit...

hi to everybody, Could someone explain me what is the exact difference between a stationary process in probability and a process arising from a dynamical system, say an observable computed along a discrete orbit? Suppose the existence of an invariant measure for the dynamical system built...

Can anyone elaborate more about this: \sum_{i=1}^n Var(Y_i-\hat{Y}_i)+[E(Y_i-\hat{Y}_i)]^2= \sum_{i=1}^nVar[(Y_i-\overline{Y}-b_1(X_i-\overline{X}))^2][/tex] How is the 2nd term combine into the variance? To be more specified: This is the intermediate step in proving E(MSE)=\sigma in...
14. ### Ring of Polynomials - and their evaluation - What is the link?

Before I ask my question some standard definitions (or rather my understanding of these definitions): Let F[x] be a ring of polynomials over a field F. i.e. F[x] is a set of symbols of the form a_0x^0 + a_1x^1 + a_2x^2 + ... + a_nx^n where a_i \in F and x is just a symbol with no meaning...
