UpperBoundType Property (BDKInput Object)

Description

For continuous data sets, specifies how the upper boundary should be treated during the fitting process. This function does not apply to discrete data sets. By default, the upper boundary type is set to the value of "unsure." You only need to set this property if you want to change this default.

Syntax

object.UpperBoundType

Arguments

None.

Return Value

(BDKBoundaryType) – one of the values:

• BDKBoundTypeUnsure – a combination of BDKBoundTypeUnbounded and BDKBoundTypeBoundedButUnknown, depending on the distribution being fitted. All distribution types can be fit in this mode. This is the default mode.
• BDKBoundTypeUnbounded - the upper bound must extend to positive infinity. Only distributions that are asymptotic to positive infinity can be fit in this mode.
• BDKBoundTypeBoundedButUnknown - the upper bound must be finite, although you want the fitting routines to determine that upper bound. Only distributions that are not asymptotic to positive infinity can be fit in this mode.
• BDKBoundTypeFixed - the upper bound is a fixed known value, which is specified in the UpperBoundValue property. Only distributions that are not asymptotic to negative infinity can be fit in this mode.

Example

'Unsure upper bound
InputObj.UpperBoundType = BDKBoundTypeUnsure
'Fixed Upper bound of 100
InputObj.UpperBoundType = BDKBoundTypeFixed
InputObj.UpperBoundValue = 100
