IBM® SPSS® Amos™ 28
Requests bootstrap standard errors for parameter estimates using the bootstrap algorithm of Efron (1982) and specifies the number of bootstrap samples.
Syntax
object.Bootstrap (nSamples)
The Bootstrap method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
nSamples |
The number of bootstrap samples. If the value of nSamples is zero, no bootstrap is performed. |
Placement: [1].
Default
No bootstrap is performed.
Remarks
Amos displays bootstrap standard errors for the estimates displayed by the methods: Standardized, Smc, FactorScoreWeights, TotalEffects, SampleMoments, ImpliedMoments and AllImpliedMoments.
Bootstrap standard errors are reported only for those quantities that are estimated. For example, to obtain bootstrapped standard errors for squared multiple correlations, you need to use the Smc method. Similarly, to obtain bootstrapped standard errors for sample correlations, you must use both SampleMoments and Standardized. Note that standard errors for estimated indirect effects are provided along with the bootstrapped standard errors of the TotalEffects method.
Bootstrap requires raw data unless you use MonteCarlo.
