IBM® SPSS® Amos™ 28
Gets the lower and upper bounds of the bootstrap confidence intervals for the elements of a matrix of estimates, using the percentile method.
Syntax
object.GetPCLowerBounds (matrixID, theMatrixBase0)
object.GetPCLowerBounds (matrixID, theMatrixBase0, groupNumber)
object.GetPCUpperBounds (matrixID, theMatrixBase0)
object.GetPCUpperBounds (matrixID, theMatrixBase0, groupNumber)
The GetPCLowerBounds and GetPCLowerBounds method syntaxes have the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
matrixID |
An integer that specifies a matrix of estimates, as described in Settings. |
theMatrixBase0 |
A double precision array, dimensioned in the calling routine as Dim theMatrixBase0() As Double or as Dim theMatrixBase0(,) As Double On return from GetPCLowerBounds each element of theMatrixBase0 contains the lower bound on the confidence interval for the corresponding element of the matrix of estimates specified by matrixID. On return from GetPCUpperbounds, theMatrixBase0 contains upper bounds. |
groupNumber |
Optional. A group number. The first group is group number 1. If groupNumber is omitted, the first group is used. |
Placement: [3].

Remarks
In order to use GetPCLowerBounds (matrixID), you must first use NeedPCLowerBounds (matrixID). For example, you have to use
object.NeedPCLowerBounds (FactorScoreWeights)
before using
object.GetPCLowerBounds (FactorScoreWeights, …)
Similarly, in order to use GetPCUpperBounds (matrixID), you must first use NeedPCUpperBounds (matrixID). For example, you have to use
object.NeedPCUpperBounds (FactorScoreWeights)
before using
object.GetPCUpperBounds (FactorScoreWeights, …)
Bootstrap can be used to specify the number of bootstrap samples. By default, 1000 bootstrap samples will be generated.
ConfidencePC can be used to specify the confidence level. By default, 90% confidence intervals will be estimated.
