Covariance models not defined about geostats.jl HOT 7 CLOSED

Hi @masiddique, the tests are passing here, perhaps you are trying to run the runtests.jl scripts directly in the Julia prompt?

The way we test packages in Julia is by running:

Pkg.test("GeoStats")

Can you please give more information?

from geostats.jl.

Yes, I was running it at the prompt. Running Pkg.test("GeoStats") works fine, so my mistake.

However, I was wondering how to pass covariance models to unikrig() function since we don't have the functions to generate such models, like GaussianCovariance() or SphericalCovariance()?

from geostats.jl.

I will document it better, thank you for your feedback. See if the example below works for you:

using GeoStats

# create some data
dim = 3; nobs = 10
X = rand(dim, nobs); z = rand(nobs)
x₀ = rand(dim)

# define a covariance model
cov = GaussianCovariance(1.,1.) # sill and range

# estimation
μ, σ² = kriging(x₀, X, z, cov=cov)
μ, σ² = unikrig(x₀, X, z, cov=cov)

from geostats.jl.

I get error:

Thank you for catching this @masiddique, I had it fixed in the master branch but forgot to tag a new version of the package in the Julia ecosystem. I will be sending the new version for approval today, meanwhile you can get it working in the development branch by typing:

Pkg.checkout("GeoStats")

This will download the latest (unstable) version of GeoStats.

from geostats.jl.

Thank you @juliohm . The example given above works now.

from geostats.jl.

@masiddique you should now be able to use the stable version again:

Pkg.free("GeoStats")

The fix was merged. Thank you again.
