Abstract :
Many a times, row-column designs are not readily available when the number of treatments is more than the levels of row and column blocking factors. One of the means to obtain new row-column designs for specific situations is through the amalgamation of two block designs in a systematic manner. Row-column designs obtained through the statistical fusion of two incomplete block designs will result in 2-part row-column designs. Algorithmic approach has also been explored for constructing series of row-column designs with incomplete rows and columns. A wide range of incomplete block designs, viz., balanced incomplete block designs/ partially balanced incomplete block designs/ t-designs, are available in the literature, which can be selected as input designs to construct such designs. To avoid the complexity involved 19 in the construction algorithm; an R package “iRoCoDe” is also developed for the generation of these designs. Further, fusion of two incomplete block designs can also yield 2-part row column designs for investigating a set of treatment combinations. Again, structurally incomplete 2-part row-column designs have been developed for situations where certain experimental units are not available for the application of treatments.
