Defintion of "noise dependence" terms -> "error dependence"

[cmaumet]

This issue is a companion for #176 to define the terms created to model noise dependence structures, namely:

• nidm:hasNoiseDependence
• nidm:NoiseDependence

( nidm:IndependentNoise, nidm:CompoundSymmetryNoise, nidm:SeriallyCorrelatedNoise, nidm:ArbitrarilyCorrelatedNoise and nidm:ExchangeableNoise discussed at STATO issue ISA-tools/stato#28).

Proposed definitions:

• nidm:hasNoiseDependence: "Property that associates a NoiseDependence with a NoiseModel "
• nidm:NoiseDependence: "Noise dependence model used to represent the dependence structure between observations used in the model parameters estimation."

Please let me know what you think. @nicholst: would you like to comment on those definitions?

How about "Model used to represent the noise-dependence structure between observations used in the full model's parameter estimation."?

[nicholst]

I like @khelm's update, but I'd finesse it further (I'm not sure what you're referring to full model... as opposed to the restricted model when doing a hypothesis test?)

"Model for the dependence structure of the error, used as part of model estimation and inference."

I'm hinting here, too, that we should give up on trying to make statements that are more general than the mass univariate GLM.

Thanks @khelm and @nicholst, I like this last update, could we further remove "and inference" to get:

"Model for the dependence structure of the error, used as part of model estimation."

And maybe we could even remove "Model" (as this is an attribute of a "Noise Model")?

"Dependence structure of the error, used as part of model estimation."

+1 from me too.

Now implemented as agreed:

• nidm:ErrorDependence: "Dependence structure of the error, used as part of model estimation." [status: Ready for release].
• nidm:hasErrorDependence: "Property that associates an ErrorDependence with an ErrorModel." [status: Ready for release].
• nidm:ArbitrarilyCorrelatedError, nidm:CompoundSymmetricError, nidm:ExchangeableError, nidm:IndependentError, nidm:SeriallyCorrelatedError [status: To be replaced by external ontology term].

I think these terms are ready for release (or will be discussed elsewhere), I will now merge.
