Hello 
I wonder how to make the exact model equation in various situation
Would you please introduce me the Textbook or Reference of good introducing of the Model Equation setting?
 
For example, I want to include 3 factors, Day, Temp, and Machine.
Machine and Temp are fixed factor and Day is random factor.
I want to make block about Day and Temp.
Thus in this situation,
How to build the model equation which looks like, 
Y=Ai+Bj(i)+Ck(ij)+el(ijk) (<--this equation is arbitrarily made)
Very confusing of how to exactly make the Paranthesis and several other rules.
 
Please help me.
