# cbrn:EquationType

A data type that describes a mathematical equation and its coefficients. The type of the equation is given by the equationKind attribute. The coefficients of the equation are supplied by the EquationCoefficients element; the values of the covariance matrix may be supplied by the EquationCovarianceMatrix. It is recommended that the data from which the equation coefficients were derived be made available as an ArrayXY type so that the coefficients for a different model could be derived.

## Content

- Sequence [1..1]
- structures:ObjectAugmentationPointAbstract [0..*]An augmentation point for ObjectType
- cbrn:RemarkText [0..*]A placeholder for comments intended to help the consumer of the data to understand better the information encapsulated by the parent element.
- cbrn:RemarksComplexObjectAugmentationPointAbstract [0..*]An augmentation point for cbrn:RemarksComplexObjectType.
- cbrn:EquationCoefficientValueList [0..*]A list of values of the coefficients of an equation.
- cbrn:EquationCovarianceMatrixValueList [0..*]A white-space delimited list of values that provide the lower triangular half of an equation covariance matrix.
- cbrn:EquationKindCode [0..*]A kind of an equation.
- cbrn:EquationDescriptionText [0..*]A free-form description of the equation type; it is intended for documentation purposes only. If the equation kind is Other, then this description shall be specified to explain the kind of equation. Polynomial equations shall report the linear term first as Term0 followed by the other terms. An example would be: Energy = Term0 + Term1*Ch + Term2*Ch**2
- cbrn:LowerLimitValue [0..*]A lowest value of X for which an equation is valid.
- cbrn:UpperLimitValue [0..*]A highest value of X for which an equation is valid.
- cbrn:EquationAugmentationPointAbstract [0..*]An augmentation point for cbrn:EquationType.
