IBM® SPSS® Amos™ 28
Gets bootstrap standard errors for the elements of a matrix of estimates.
Syntax
object.GetStandardErrorsEx (matrixID, am, groupNumber)
The GetStandardErrorsEx method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
matrixID |
An integer that specifies a matrix of estimates, as described in Settings. |
am |
An object of type AmosMatrix. On return from GetStandardErrorsEx, am contains bootstrap standard errors for the elements of the matrix of estimates specified by matrixID. |
groupNumber |
Optional. A group number. The first group is group number 1. If groupNumber is omitted, the first group is used. |
Placement: [3].
Settings
The settings for matrixID are:
Constant |
Value |
Description |
SampleCovariances |
13 |
Sample covariances. |
SampleCorrelations |
14 |
Sample correlations. |
SampleMeans |
15 |
Sample means. |
ImpliedCovariances |
10 |
The implied covariances among the observed variables in the model. |
ImpliedCorrelations |
11 |
The implied correlations among the observed variables in the model. |
ImpliedMeans |
12 |
The implied means of the observed variables in the model. |
AllImpliedCovariances |
7 |
The implied covariances among all variables in the model, with the exception of residual variables. |
AllImpliedCorrelations |
8 |
The implied correlations among all variables in the model, with the exception of residual variables. |
AllImpliedMeans |
9 |
The implied means of all variables in the model, with the exception of residual variables. |
DirectEffects |
19 |
Direct effects. |

Indirect effects. |
TotalEffects |
5 |
Total effects. |
StandardizedDirectEffects |

23 |
Standardized indirect effects. |
StandardizedTotalEffects |
21 |
Standardized total effects. |
FactorScoreWeights |
6 |

Remarks
You have to use NeedStandardErrors to declare that standard errors for a matrix will be needed before you can use GetStandardErrorsEx to obtain the standard errors. For example, you have to use
object.NeedStandardErrors (StandardizedTotalEffects)
before using
object.GetStandardErrorsEx (StandardizedTotalEffects, …)
GetStandardErrorsEx differs from GetStandardErrors in the following way. GetStandardErrorsEx assigns values to the members of an AmosMatrix object, which contains the matrix of standard errors as well as the variable names and variable numbers associated with the matrix's rows and columns. GetStandardErrors , by contrast, merely sets a double array equal to the matrix of standard errors. Additional calls to RowNames, RowNumbers, ColumnNames and ColumnNumbers are necessary if there is a need for the variable names and variable numbers associated with the matrix's rows and columns.
GetStandardErrorsEx is often more convenient, but GetStandardErrors is faster.
