Algorithm: Logistic Regression

As I previously mentioned in my Linear Regression post, linear regression works best with regression type problems.  Linear regression wouldn't work well on classification problem since only numeric values on a continuous interval would be returned.  Now, you could describe a range to classify the test case when an interval is reached, but it's not very good practice to use the algorithm in this manner.

So if you can't use linear regression for classification, what kind of algorithm can be used to classify test cases?  While there are many different algorithms that can be used in classification, one of the most basic algorithms is logistic regression.
