Correction: Square Array Designs for Unreplicated Test Treatments with Replicated Controls

In this article, the equation in the statement of Theorem 3. The numerator of the right-most fraction has two minus signs in it, but it should only have one.In this article, In the penultimate line in the equation-array near the end of the proof of Theorem 3, there is a comma at the end of the line.That comma should not be there.In this article, A few lines before the start of Section 4.2.2, "Equations ( 7)" should be "Equation ( 7)."In this article, In the heading of Table 4, the phrase "Number of controls k" should be left-aligned with the number 3 in the next line.In this article, In the first sentence after Example 4, "is shown in Table 6" should be "are shown in Table 6."In this article, Three lines before the start of Section 6, "Example 3" should be "Example 2."In this article, in the text of Example 1, "Fig.2b" should be "Fig.2(b)".In this article, in the text of Example 2, "Fig.1a" should be "Fig.1(a)" and "Fig.1b" should be "Fig.1(b)".In this article, in the text of Example 3, "Fig.4a, b" should be "Fig.4(a), (b)".In this article, in the text of Example 4, "Fig.4c" should be "Fig.4(c)".In this article, In the References, in the paper by Jger et al, the word "youden" should be "Youden" in both occurrences, because Youden squares are named after the statistician Youden.
