Thus, however weary a man might be, he never liked to lie in the bed of Procrustes
Finally, Unweighted Pair Group Method with Average (UPGMA) was computed from the Procrustes
distances obtained through ventral side configurations.
Para determinar la variacion atribuible al error cometido al marcar los landmarks, se realizaron pruebas de repetibilidad (Harper, 1994; Arnqvist & Martensson, 1998) sobre las variables obtenidas despues de marcar dos veces los puntos sobre cada una de las 276 imagenes incluidas en este estudio: el tamano centroide, las coordenadas alineadas despues de la superposicion de Procrustes
y las variables RW.
methods were used to analyze shape by superimposing configurations of landmarks into two or more specimens to achieve an overall best fit.
Relationships between the multivariate analyses (environmental variables and structure of periphytic diatom assemblage) were examined by a Procrustes
analysis (PERES-NETO; JACKSON, 2001).
We checked the similarity of particular pairs of solutions by calculating two indices: (1) the product-moment correlation r between their respective sets of inter-point distances, and (2) the least-squares Procrustes
In order to compare shape, the coordinates for each specimen in this study were scaled, aligned and transformed by General Procrustes
Alignment (GPA) using the software TpsRel 1.
Like a voice from the grave, Paul Marchand might have been a racial jeremiad or an enlarged version of "Baxter's Procrustes
," a sly satire on authorship, publication, and literary fame.
Analisis de morfometria geometrica: A partir de la matriz de 168 configuraciones de coordenadas geometricas de los ocho puntos (PAR1-PAR8), se realizo el Analisis Generalizado de Procrustes
, con el programa CoordGen (Sheets 2005a) para una superimposicion Procrustes
y luego extraer una matriz con las variables de conformacion (Partial warps=Pw) y tamano centroide (CS).
ramburii modules: Geometric morphometric tools that include landmark-based and procrustes
methods were used to extract shape information from coordinate data in a set of steps that eliminate reflection and variation in scale, position and orientation (Rohlf, 2002, 2004, 2006, 2007 and 2008).
analysis (JACKSON, 1995) with 10,000 permutations were run for each group of two variables (for example Copepoda and Cladocerans, or Copepoda and environmental variables), using the scores of the two first axis of each ordination above, resulting in the "r" value for concordance between two sets of data that varies from 0 (absence of concordance) and 1 (perfect concordance).
Comparison of the factor solutions with varimax rotation for the three samples was made using congruence analysis, following the orthogonal procrustes
rotation method used by Aluja, Garcia, and Garcia (2003), and the interpretation of congruence coefficients, in accordance with Chico, Tous, Lorenzo-Seva, and Vigil-Colet (2003).
