Construction Of Incomplete Counterbalancing For Immediate Sequential Effects Crossover Design

Crossover designs are useful in many areas such as pharmaceutical industry clinical trial educational experiment and so on. Different construction methods for crossover design have been developed so far. In this paper our purpose is to construct incomplete counterbalancing for immediate sequential effects where all treatments do not occur within the same subject or the same period. Here we constructed incomplete sequentially counter balanced crossover design by removing the last period and the last subject for column and row method approach respectively. The result shows that all treatments do not occur within the same subject and each treatment is precede by each other treatment once and unequal number of times for even number and odd number respectively for column method approach also all treatments do not occur within the same period and each treatment is precede by each other treatment twice and unequal number of times for even number and odd number respectively for row method approach. It is not uniform design for not all the treatments appear in each subject and each period for column and row method respectively.
