Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Factor replicability is more likely when factors have at least four measured variables with structure coefficients > |.6|, irrespectively of the size of the sample.

    “They proposed that factor replicability is more likely when: 1) factors have at least four measured variables with structure coefficients > |.6|, irrespectively of the size of the sample;”
  • The crucial parameter in EFA sample size is the degree of factor saturation by the measured variables.

    “In a similar vein, the Monte Carlo simulation work by Guadagnoli and Velicer (1988) suggested that the crucial parameter in EFA sample size is the degree of factor saturation by the measured variables.”
  • For N > 150, factors are defined with 10 or more structure coefficients of about |.4| (and low p/m ratio), when 300 ≤ N ≤ 400.

    “2) for N > 150 factors are defined with 10 or more structure coefficients of about |.4| (and low p/m ratio), when 300 ≤ N ≤ 400 (Guadagnoli & Velicer, 1988: p. 274 quoted in Dimitrov, 2012).”
  • Strength of item loadings, uniformity of the communalities, and number of items per factor ('strong data') are vital for the stability, reliability, and replicability of a factor solution.

    “studies suggest that strength of item loadings, uniformity of the communalities and number of items per factor (Guadagnoli & Velicer, 1988) or in two words 'Strong data' (Costello & Osborne, 2005) are vital for the stability, reliability, and replicability of a factor solution (Wang et al., 2013).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
