Conseqüências da análise incorreta de experimentos blocados The consequences of incorrect analysis of blocked experiments

open access: yesQuímica Nova, 2007
Errors are always present in experimental measurements so, it is important to identify them and understand how they affect the results of experiments. Statistics suggest that the execution of experiments should follow random order, but unfortunately the ...

Incomplete split-plots in variety trials - based on a-designs [PDF]

open access: yes, 2003
Incomplete split-plots based on a-designs are proposed as alternative to traditional split-plot designs. The purpose of the incomplete split-plot designs is to increase the efficiency of the treatment (whole plot factor) comparisons especially for ...

Selection and Screening Procedures to Determine Optimal Product Designs. (REVISED, April 1997) [PDF]

open access: yes, 1996
To compare several promising product designs, manufacturers must measure their performance under multiple environmental conditions. In many applications, a product design is considered to be seriously flawed if its performance is poor under any level of

Optimal Designs For the Restricted Maximum Likelihood Estimators in a Random Split-Plot Model

open access: yesLithuanian Journal of Statistics, 2017
The design effect for the restricted maximum likelihood estimators of variance components in acompletely randomized split-plot model is studied. The model was used to represent the response generated froman experimental scenario where the whole-plot and
