- i
- denote experiment number (i.e., 1,2,3,4)
- j
- denote replication (i.e., 1,2,3)
- y_{ij}
- observed response value in j-th replication of i-th experiment
- yhat_i
- estimated response using our model equation when factors have levels corresponding to experiment i
- ybar_{..}
- mean of responses from all replications of all experiments
- ybar_{i.}
- mean of responses from all replications of experiment i
Experimental error e_{ij}: difference between measured and estimated responses for jth replication of ith experiment:
