Setting the optimize configuration
DistributionFits.AbstractDistributionFitOptimizer
— TypeAbstractDistributionFitOptimizer
OptimOptimizer <: AbstractDistributionFitOptimizer
set_optimizer(::AbstractDistributionFitOptimizer)
DistributionFits.jl
uses the following interface to opimize an univariate function f
on bounded interval [lower,upper]
:
optimize(f, ::AbstractDistributionFitOptimizer, lower, upper)
Returning an object with fields minimizer
and converged
.
DistributionFits.set_optimizer(::AbstractDistributionFitOptimizer)
sets the optimizer used in calling the optimize function. Specializing this function with a concrete type, allows using different optimization packages.
By default, when the Optim.jl package is in scope, the OptimOptimizer
is set, which implements the interface by using Optim's optimize function.
Hence, the module using DistribuitonFits.jl has to either
- explicitly invoke
using Optim
, or - call
set_optimizer
with the concrete subtype ofAbstractDistributionFitOptimizer
for which the corresponding optimize method is implemented.
