jim-data-analysis【设计与创意】Use when estimating and reporting results for a Journal of International Marketing (JIM) manuscript — measurement-invariance testing (MGCFA/alignment), multilevel models with country-level predictors, multi-group SEM, and multi-country panels. It executes and reports; jim-methods designed the study.

Run the MGCFA ladder per construct, in order, and report every rung:
| Step | Constraint added | Licenses you to… |
|---|---|---|
| Configural | same factor structure | claim the construct exists everywhere |
| Metric | equal loadings | compare structural paths / correlations across countries |
| Scalar | equal intercepts | compare latent means across countries |
Decision rules: χ² difference plus practical criteria (ΔCFI ≤ .01; monitor ΔRMSEA). When full invariance fails: release the minimum number of parameters for partial invariance (at least two invariant items per construct, per the Steenkamp–Baumgartner protocol) and restate exactly which comparisons remain licensed. With many countries (8+), pairwise MGCFA explodes — use the alignment method and report the proportion of non-invariant parameters (≤25% rule of thumb). If scalar invariance dies and cannot be partially rescued, mean-comparison hypotheses are off the table; say so in the paper rather than burying it.
Also run: response-style controls (model ARS/ERS factors or covariates as planned in design) and per-country reliability/validity (CR, AVE, discriminant checks reported for each country, not pooled).
| Data structure | Estimator | Reporting keys |
|---|---|---|
| Consumers nested in countries (10+ countries) | Multilevel / HLM with country-level predictors | ICC first; random slopes for moderated effects; group-mean vs. grand-mean centering stated |
| Few countries (2–4) | Multi-group SEM with invariance constraints | path-difference tests across groups, not eyeballed coefficients |
| Cross-level moderation | random-slope HLM or MSEM | the slope variance must be nonzero before a country variable can explain it |
| Firm export panels | FE / DiD (staggered-adoption estimators) / selection models | cluster at firm or country per the variation; pre-trends where causal |
| Country dyads (home–host) | dyadic models with distance variables | control both origin and destination effects |
| Meta-analytic | random-effects + meta-regression on country dimensions | between-study heterogeneity decomposed |
Small-N-countries warning: with fewer than ~10 countries, country-level regression coefficients are unstable — prefer multi-group contrasts, fixed effects, or Bayesian multilevel with informative priors, and never narrate 5 countries as a "test" of a continuous cultural dimension.
Run the battery end-to-end instead of enumerating it. Full map: execution-with-mcp. For JIM's structures: multi-country panels via detect_design → recommend → fit with as_handle=true → audit_result; staggered policy variation via callaway_santanna / sun_abraham with honest_did_from_result; few-cluster (few-country) inference via wild_cluster_bootstrap; many-outcome hypothesis families via romano_wolf; OVB sensitivity via oster_delta / sensemakr; exhibits exported from the result handle (etable) so no number is retyped. HLM and measurement-invariance runs (MGCFA ladders, alignment) execute in lavaan/Mplus-lane scripts under resources/code/ — keep the per-step fit log as the audit trail; SEM path models follow the same handle-then-audit discipline.
【Invariance】per construct: configural/metric/scalar (full/partial/alignment) + decision rule
【Licensed comparisons】means / paths / neither — per construct
【Estimator】structure-matched model + clustering/centering choices
【Country-difference tests】formal Δ-tests for each claimed difference: done?
【Managerial magnitude】headline effect in cross-border decision units
【Robustness】response styles / small-N limits / identification threat addressed
