How to resolve Non convergence problem in fitting Unstructured and Factor analytic variance-covariance model using ASREML-R?

Dear All, I am using ASREML-R to fit unstructured (UN) and factor analytic (FA) model to explore complex structure of genotype by environment interaction in multienvironment yield data. There are...

How can I calculate point density in interpolation grid?

A GSTAT library of R was used to generate a grid size of (i) 10 x 10 m and (ii) 10 x 5 m running from an Easting of 299677 m to 301297 m and a Northing of 5737278 m to 5738128 m. This resulted in...

How can I obtain a standard error of variogram parameters estimate from a gstat package?

A number of variogram models were fitted where estimates like nugget, range, and sill were obtained from gstat of R. Could anyone guide me on how to obtain standard error for each of these...

How do I figure out the parameter estimate of a matern and exponential variogram model?

I used gstat to fit a Matern variogram model to my crop yield by setting the kappa = 0.5. To my surprise, its parameter estimates are exactly the same with that of exponential. Does it mean that...
