This paper considers an experimentation strategy when resource constraints permit only a single design replicate per time interval, and one or more design variables are hard-to-change. The experimental designs considered are two-level full or fractional factorial designs run as balanced split-plots. These designs are common in practice and appropriate for fitting a main effects plus interaction...

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 awed if its performance is poor for any level of the environmental factor For example if a particular automobile battery design does not function well under temperature extremes then a manufacturer m...

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 the environmental factor. For example, if a particular automobile battery design does not function well under some temperature conditions, then...

Microarray applications for the study of gene expression are becoming accessible for researchers in more and more systems. Applications from field or laboratory experiments are often complicated by the need to superimpose sample pairing for two-color arrays on experimental designs that may already be complex. For example, split-plot designs are commonly used in biological systems where experime...

Restricting the randomization of hard-to-change factors in industrial experiments is often performed by employing a split-plot design structure. From an economic perspective, these designs minimize the experimental cost by reducing the number of resets of the hard-tochange factors. In this paper, unbalanced designs are considered for cases where the subplots are relatively expensive and the exp...

In this research, effect of vermicompost and plant growth promoting rhizobacteria (PGPR) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at Karaj Research Institute of Forest and Rangelands. Experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...

این آزمایش با طرح آماری کرتهای خرد شده نواری (strip split plot) در قالب بلوکهای کامل تصادفی با 4 تکرار، در شرکت زراعی دشت ناز ساری، در سال 1378 اجرا گردید. عامل تراکم در چهار سطح( 5/5 ، 6/5 ، 7/5 و 8/5 بوته در متر مربع) و عامل فاصله ردیف در سه سطح(55 ،65 و 75 سانتی متر) در نظر گرفته شد. خصوصیات رویشی و زایشی گیاه در زمان های مورد نظر اندازه گیری و برآورد گردید.

The split-plot design arose from agricultural science with experimental units, also known as the subplots, nested within groups whole plots. It assigns different interventions at whole-plot and subplot levels, respectively, providing a convenient way to accommodate hard-to-change factors. By design, subplots same plot receive level of intervention, thereby induce group structure on final treatm...
