Specific residue: application of orthogonal contrasts when heteroscedasticity is present Resíduo específico: aplicação de contrastes ortogonais na presença da heterocedasticidade

open access: yesScientia Agricola, 2010
When experimental data are submitted to analysis of variance, the assumption of data homoscedasticity (variance homogeneity among treatments), associated to the adopted mathematical model must be satisfied.

Decomposition tables for experiments I. A chain of randomizations [PDF]

open access: yes, 2009
One aspect of evaluating the design for an experiment is the discovery of the relationships between subspaces of the data space. Initially we establish the notation and methods for evaluating an experiment with a single randomization.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Decomposition tables for experiments. II. Two--one randomizations [PDF]

open access: yes, 2010
We investigate structure for pairs of randomizations that do not follow each other in a chain. These are unrandomized-inclusive, independent, coincident or double randomizations.
