in this paper, we propose space-time block codes based on constituent intersectant orthogonal designs. after channel model is formulated, we studied the space-time block codes from constituent intersectant orthogonal designs. at last we made simulations for the space-time block codes from complex orthogonal design and the space-time block codes from constituent intersectant orthogonal design to...

The Cochran–Mantel–Haenszel (CMH) tests apply when every treatment is present on block or stratum and responses are categorical. This chapter explains the most elementary of incomplete designs, balanced design (BIBD), in part to see how CMH methods can aid analysis for such designs. relationship shows that adjusted Durbin test ANOVA F essentially same test, so both equality mean ranks, not mere...

durbin's rank test is widely used for testing treatment effects in balanced incomplete block designs (bibds)which have wide applications in sensory analysis. this test is failed for bibds when ties data occur. an adjusted version of durbin rank test for this kind of data is given to solve this problem. chi-square approximation, which is commonly used for this test, is not adequate for small bib...

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 ...
