IBM® SPSS® Amos™ 28

Controls whether bootstrap confidence intervals obtained by using the percentile method (Efron, 1987) are reported.

Syntax

object.ConfidencePC (confidenceLevel)

The ConfidencePC method syntax has the following parts:

Placement: [1].

Default

Percentile confidence intervals are not reported.

Remarks

Amos can produce bootstrapped confidence intervals for all parameter estimates, as well as for estimates displayed by the methods: Standardized, Smc, FactorScoreWeights, TotalEffects, SampleMoments, ImpliedMoments and AllImpliedMoments.

Bootstrap confidence intervals 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.

When you use ConfidencePC, you must also use Bootstrap to specify the number of bootstrap samples. Note that percentile confidence intervals for estimated indirect effects are provided along with the percentile confidence intervals of the TotalEffects method.

ConfidencePC requires raw data unless you use MonteCarlo.
