Finding Informative Features - CMU Statistics

Similarly, our uncertainty about the class C, in the absence of any other information, is just the entropy of C: H[C] = X c Pr(C= c)log 2 Pr(C= c) Now suppose we observe the value of the feature X.

Degrees of Freedom and Model Search - CMU Statistics

Degrees of Freedom and Model Search Ryan J. Tibshirani Abstract Degrees of freedom is a fundamental concept in statistical modeling, as it provides a quan-titative description of the amount of tting performed by a given procedure. But, despite this
