Logistic Regression - Carnegie Mellon University
www.stat.cmu.edu12.1 Modeling Conditional Probabilities So far, we either looked at estimating the conditional expectations of continuous variables (as in regression), or at estimating distributions. There are many situations where however we are interested in input-output relationships, as in regression, but the output variable is discrete rather than continuous.

X, we can only talk aboutprobability within an interval X 2(x;x + x) p(x) x is the probability that X 2 (x;x + x) as x ! 0 The probability density p(x) satis es the following p(x) 0 and Z x p(x)dx = 1 (note: for continuous r.v., p(x) can be >1) (IITK) Basics of Probability and Probability Distributions 5

Probability - University of Cambridge
www.statslab.cam.ac.uk5.The probability that humanity will be extinct by 2100 is about 50%. Clearly, these are quite di erent notions of probability (known as classical1;2, frequentist3 and subjective4;5 probability). Probability theory is useful in the biological, physical, actuarial, management and com-puter sciences, in economics, engineering, and operations ...
