matrix data

A two-level model, with one explanatory variable at the individual level (X) and one explanatory variable at the group level (Z): Y_{ij}=\gamma_{00}+\gamma_{10}X_{ij}+\gamma_{01}Z_{j}+\gamma_{11}X_{ij}Z_{j}+u_{0j}+u_{1j}X_{ij}+e_{ij}\ldots (1) correlation between u_{0j} and u_{1j} is 0 . The...

Hello all! My research examined if social behaviors in animals changed with the distribution of food treatment (clumped vs. dispersed food). My data is non-parametric. I have matrices of interaction rates between individuals. I ran Mantel tests between the interaction matrices of the...

Hello everyone, My question is a bit unusual, since it is not about the program itself, but regarding the data. I have a matrix representing (reverse) distance between each pair of objects. In SEM, we usually work with correlations. A higher correlation represents variables that are closer...

I need to generate bootstrapped data sets from matrix with the following constraints: 1. The row sums remain constant, i.e., the same as the original matrix 2. Autocorrelations for each matrix row in the original matrix is preserved How do I go about this? My understanding is that there are...
