The F.D.A. is calling these tests "multivariate index assays".
We next derived a multivariate index of target processing at the exemplar versus category level by classifying trials according to the level at which the target search was directed, i.e. either exemplar-level or category-level.
ANA: antibody to nuclear antigens; FDA US Food and Drug Administrationn; IVDMIA: in vitro diagnostic multivariate index assay; RA: rheumatoid arthritis.
In a multivariate logistic regression model, after adjustment for sex and Charlson index, there was no statistically significant difference between cases and controls for IS, VS and VIS (p = ns).
This article compares the performance of multivariate analysis of variance (MANOVA) technique to that of multivariate indices.
The methodology joins recent developments achieved in multivariate and regional HFA, such as copulas, multivariate quantiles and the multivariate index-flood model.
In the multivariate model the odds ratio for the TOP2A/β-tubulin index was 1.33, which indicated that for each unit increase (i.e. from −3 to −2, from 0 to 1, or from 4 to 5, etc) in the AT index, there was a 1.33 times increase in the odds of a patient experiencing complete pathological response.
A multivariate ENSO index, MEI48, is shown with vertical color shading, where red and blue shades denote respective positive (El Niño) and negative (La Niña) phases, and darker shades indicate greater MEI intensity.
The ENSO driven climate oscillations impart clear impacts to global P, indicated by significant negative correlation between the annual MEI (Multivariate ENSO Index) and annual P (r = −0.71; P < 0.001).
Climatic anomalies included were multivariate ENSO index, quasi-biennial oscillation and North Atlantic Oscillation.
