Dear all, I'm trying to estimate Moran's I using the moran.test function Below please find the summary statistics for my network and key variable. In doing so, I'm facing the issue that my estimation results in the following error message:
Warning message: In moran.test(x, Network_): Out-of-range p-value: reconsider test arguments The results are as follows: Moran's I test under randomisation data: x weights: Network Moran I statistic standard deviate = NA, p-value = NA alternative hypothesis: greater sample estimates: Moran I statistic Expectation Variance -Inf -0.0002926544 NA Could anyone please tell me what this error message means? Is there a problem with my network and/ or with my key variable? Thanks very much for letting me know, Michael Characteristics of weights list object: Neighbour list object: Number of regions: 3418 Number of nonzero links: 6442 Percentage nonzero weights: 0.05514125 Average number of links: 1.884728 Non-symmetric neighbours list Weights style: NA Weights constants summary: n nn S0 S1 S2 NA 3418 11682724 0 NA NA summary(x) Min. 1st Qu.
