Question

Which of the following statement is NOT correct?

a. If we have no complete separation, then we cannot draw a vertical line that separate all the zeros and ones
b. Complete separation occurs when one or more variables classifies the observations into successes and failures perfectly
c. If we have complete separation, we can separate all the zeros and ones with a single vertical line in a scatterplot of X versus Y
d. No complete separation means that one or more variables classifies the observations into successes and failures perfectly

Answer 1

Option d, 'No complete separation means that one or more variables classifies the observations into successes and failures perfectly,' is not correct.

Step-by-step explanation:

The correct statement is option d: No complete separation means that one or more variables classifies the observations into successes and failures perfectly.

Complete separation occurs when one or more variables classifies the observations into successes and failures perfectly, which makes option b correct. If we have complete separation, we can separate all the zeros and ones with a single vertical line in a scatterplot of X versus Y, making option c correct. If we have no complete separation, then we cannot draw a vertical line that separates all the zeros and ones, making option a correct.
