| Discriminant Function Analysis |

| | Therefore, variable height allows us to **discriminate** between males and females with a better than chance probability: if a person is tall, then he is likely to be a male, if a person is short, then she is likely to be a female. |

| | In the two-group case, **discriminant** function **analysis** can also be thought of as (and is analogous to) multiple regression (see Multiple Regression; the two-group **discriminant** **analysis** is also called Fisher **linear** **discriminant** **analysis** after Fisher, 1936; computationally all of these approaches are analogous). |

| | In general **Discriminant** **Analysis** is a very useful tool (1) for detecting the variables that allow the researcher to **discriminate** between different (naturally occurring) groups, and (2) for classifying cases into different groups with a better than chance accuracy. |
