a.
Identify the meaning of a procedure to be a “special case” of another procedure.
a.
Answer to Problem 1.1HD
The special case is a procedure that can be derived mathematically from the other procedure. The special case is mathematically identical except it is used in a more limited number of situations.
Explanation of Solution
The procedure is said to be special case of another if the procedure is derived from the formula of another procedure. And the results obtained from the special case are same as the results obtained by another procedure unless it is applied in more limited situations.
Thus, the special case is a procedure that can be derived mathematically from the other procedure and it is mathematically identical except it is used in a more limited number of situations.
b.
Identify which procedures are special cases of which.
b.
Answer to Problem 1.1HD
The analysis of variance and bivariate prediction are special cases of multiple regression and t test is a special case of analysis of variance and bivariate
Explanation of Solution
The most commonly used technique is multiple regression. The bivariate correlation and prediction, the analysis of variance are special cases of multiple regression. And t test is derived either from analysis of variance or bivariate correction directly.
Thus, the analysis of variance and bivariate prediction are special cases of multiple regression and t test is a special case of analysis of variance and bivariate correlation
