  • What is translation invariance in computer vision and convolutional . . .
    Invariance vs Equivariance Santanu_Pattanayak's answer (here) points out that there is a difference between translation invariance and translation equivariance Translation invariance means that the system produces exactly the same response, regardless of how its input is shifted
  • modeling - Clarification on Δχ² interpretation for metric invariance . . .
    “Metric invariance is supported when ΔRMSEA ≤ 0 01 in conjuction with sig chi-square difference test and ΔCFI ≥ – 004 for metric" In other words, this means that even if the chi-square difference test is significant (p < 0 05), but ΔCFI and ΔRMSEA stay within acceptable thresholds , metric invariance can be considered supported?
  • Invariance property of maximum likelihood estimator?
    Invariance property of maximum likelihood estimator? Ask Question Asked 12 years, 3 months ago Modified 7 years, 3 months ago
  • factor analysis - Measurement invariance testing with ordinal data . . .
    I've been trying to wrap my head around measurement invariance testing with ordinal data in R version 4 2 2 using lavaan 0 6-13 It all seemed rather straight-forward in theory, but I believe I am
  • Measurement invariance and latent mean comparison between 3 groups
    I then ensured measurement invariance across these groups, achieving configural, metric, and scalar invariance For the final analysis phase, I aim to compare the latent means of the two factors across these groups For instance, I am interested in determining whether Factor 1 is statistically higher in Group 2 compared to Group 3
  • What does shift invariant mean in convolutional neural network?
    I saw a term describing the feature detectors, i e shift invariant What is that mean? Paper: 1989 Generalization and Network Design Strategies
  • Intuitive explanation of invariance - Cross Validated
    Invariance is a relative property not an absolute one Something is described as invariant under some manipulation For a non-mathematical (and hence non-statistical) example we consider the egg The shape of an egg is invariant under boiling (it remains egg-shaped) The shape of an egg is not invariant under poaching, frying, scrambling, making and omelette The separate integrity of the yolk
  • What is the substantive meaning of scalar invariance?
    5 I understand that scalar invariance, in the context of Structural Equations Modeling (SEM), is having the intercepts for observed variables loading on the same latent variable be invariant across multiple groups However - what does scalar invariance mean substantially? What are its implications?
