Statistical comparison of Schlumberger arrays using randomized complete block design

relative efficiency of alpha lattice design over randomized complete block design in yield trials of chickpea (cicer arietinum l.)

structure of alpha lattice designs makes removing the effects of incomplete blocks from residual effect of plots, and maximizes precision of comparison between genotypes at the same incomplete block. this investigation was conducted to study the international chickpea germplasm, for finding desirable lines regarding seed yield and other traits. two trials including cien-la-2010 and cien-s-2010 ...

Randomized Block Design

Example It is common in nutrition studies to compare diets by feeding them to newly weaned male rats and measuring the weight gained by the rats over a 28-day period. The initial weight of the rats is an extraneous factor that is especially important as an influence on weight gain. Rather than randomly assign 10 rats to each diet, we first divide the animals into 10 groups of 3 rats each based ...

Hyperkalemia-induced complete heart block

Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...

Series of randomized complete block experiments with non-normal data

Randomized complete block designs are common in agricultural and other experiments. In this manuscript, we derive asymptotic procedures as well as finite approximations, for the analysis of data arising from series of such experiments. We do not assume normality of the data, and the within-block covariance structures can be arbitrary (no restriction to compound symmetry). The methods are specif...
