# missing-plot technique

views updated Jun 27 2018

missing-plot technique A standard formula for the estimation of a missing datum observation (or, with suitable modification, the estimation of several missing values) in the analysis of the variance of data collected according to a recognized experimental design. The missing observation (xij) may be estimated as: xij = tTj+bBjG′/(t−1)(b−1) where Tj, bBj, and G′ are the treatment, block, and grand totals for the available observations, i is the ith treatment, j is the jth block, t is the number of treatments, and b is the number of blocks.

missing-plot technique Standard formula for the estimation of a missing datum observation (or, with suitable modification, the estimation of several missing values) in the analysis of the variance of data collected according to a recognized experimental design. The missing observation (xij) may be estimated as:

xij = (tTi + bBjG′) / (t − 1) (b − 1),

where Ti, Bj, and G' are the treatment, block, and grand totals for the available observations, i is the ith treatment, j is the jth block, t is the number of treatments, and b is the number of blocks.
