Hello list(s) and sorry for cross-posting, I would like to generate random data on a grid with a given level of spatial autocorrelation (Moran's I). Is there a method (and a software) to do it ? Thanks in...

Hello, I have search on R website but do not find any solution. I would like to know if R has some functionalities to produce analytical results of equation. or more generally if it contains some functions to simplify equation...

Hello list, Sorry, these questions are not directly linked to R. If I consider an indefinte real matrix, I would like to know if the symmetry of the matrix is sufficient to say that their eigenvectors are real ? And what...
