The DStDevP function calculates the standard deviation across a population in a specified set of records. _________________________

Repeat the previous analysis assuming that the classifier predicts each test record to be positive class with probability 2/3 and negative class with probability 1/3.

Consider the task of building a classifier from random data, where the at- tribute values are generated randomly irrespective of the class labels. Assume the data set contains records from two classes, “+” and “?.” Half of the data set is used for training while the remaining half is used for testing.

Name the four basic activities that are involved in a software development process.

What will be an ideal response?
