Even if these empirical disciplines were considerably more advanced than they presently are, the most they could disclose is the exact process that goes on in a being's head when he or she (or it) is reasoning. They could not, however, tell us whether the being is reasoning correctly or incorrectly.

Regression with a Binary Dependent Variable - Chapter 9

Logit or Logistic Regression Logit, or logistic regression, uses a slightly di erent functional form of the CDF (the logistic function) instead of the standard normal CDF. The coe cients of the index can look di erent, but the probability results are usually very similar to the results from probit and from the LPM.

Propositional Logic - University at Buffalo

The Foundations: Logic and Proof The rules of logic specify the precise meanings of mathematical statements. It is the basis of the correct mathematical arguments, that is, the proofs. It also has important applications in computer science: to verify that computer programs produce the correct output for all possible input values.

Propositional logic deals with such statements and compound propositions that combine together simple propositions (e.g., combining sentences (1) and (2) above we may say “Warsaw is the capital of Poland and 2 + 5=3 ”). In order to build compound propositions we need rules on how to combine propositions. We
