RBD.miss {Missplot}

Analysis of RBD when there is one missing observation

Description

Analysis of RBD when there is one missing observation

Usage

RBD.miss(data, bl.miss, trt.miss)

Arguments

data

A data-frame containing response in the first column , block number in the second column, treatment number in the third column corresponding to the response value.

bl.miss

Block number corresponding to the missing observation.

trt.miss

Treatment number corresponding to the missing observation.

Details

In design of experiments in RBD setup if there is one missing observation present in the design , we can use the function RBD.miss to estimate the missing observation for testing the differential effects for the treatments. Here, we estimate the missing obsevation by minimizing the SSE of the design.

Value

A data-frame containing x.hat , SSE x.hat , x_double.hat , SSE x_double.hat, F statistics , p-value.
