Pruning Decision Trees With Misclassification Costs, Jeffrey P. Bradford, Clayton Kunz, Ron Kohavi, Cliff Brunk, Carla E. Brodley
Pruning Decision Trees With Misclassification Costs, Jeffrey P. Bradford, Clayton Kunz, Ron Kohavi, Cliff Brunk, Carla E. Brodley
Department of Electrical and Computer Engineering Technical Reports
decision tree classifiers in two learning situations: minimizing loss and probability estimation. In addition to the two most common methods for error minimization, CART'S cost-complexity pruning and C4.5'~ errorbased pruning, we study the extension of cost-complexity pruning to loss and two pruning variants based on Laplace corrections. We perform an empirical comparison of these methods and evaluate them with respect to the following three criteria: loss, mean-squared-error (MSE), and log-loss. We provide a bias-variance decomposition of the MSE to show how pruning affects the bias and variance. We found that applying the Laplace correction to estimate the probability distributions at …
Expectations Formation And Inflation Persistence, J. A. Carlson, Neven Tomov Valev
Expectations Formation And Inflation Persistence, J. A. Carlson, Neven Tomov Valev
Purdue CIBER Working Papers
This paper studies the dynamics of inflation if monetary policy is transparent only to part of the population. We find that average long-run inflation decreases in the proportion of agents with naive expectations and, because of tradeoffs between speed of adjustment and long-run inflation, central banks prefer a higher proportion of agents who form informed expectations in high inflation periods but not so in lower inflation periods. We use survey data on expectations of inflation from Bulgaria collected at the time a currency board was introduced in that country to test for influences on the heterogeneity of expectations across agents.
Trade Reduction, Diversion And Compression: Empirical Regularities In The Effects Of Protective Measures, Jon D. Haveman, Reichert U. Nair, Jerry Thursby
Trade Reduction, Diversion And Compression: Empirical Regularities In The Effects Of Protective Measures, Jon D. Haveman, Reichert U. Nair, Jerry Thursby
Purdue CIBER Working Papers
We analyze the effectiveness of protective measures in a differentiated products framework using highly disaggregated data. The extent of the data and level of disaggregation permits us to separate the aggregate effect of tariffs and non-tariff barriers (NTBs) into reduction, diversion and compression effects.
Determinants Of Currency Risk Premiums, J. A. Carlson, C. L. Osler
Determinants Of Currency Risk Premiums, J. A. Carlson, C. L. Osler
Purdue CIBER Working Papers
The risk premium is a function of both the interest rate differential and the gap between the current exchange rate and its long-run equilibrium in a model of the foreign exchange market with both non-speculating traders and rational speculators. If the speculators have an alternative to specializing in exchange-rate speculation, then there should be no presumption that uncovered interest rate parity will hold even approximately with a long-run equilibrium number of speculators. Furthermore, when other traders respond to interest-rate differentials, the model can give rise to a negative relationship between the interest-rate differential and the subsequent change in the exchange …
International Integration And Growth: A Survey And Empirical Investigation, Jon D. Haveman, V. Lei, J. S. Netz
International Integration And Growth: A Survey And Empirical Investigation, Jon D. Haveman, V. Lei, J. S. Netz
Purdue CIBER Working Papers
After surveying the theoretical and empirical work, we attempt a comprehensive assessment of different forms of international integration on growth. In particular, we consider the impact of trade, of inward foreign direct investment, of preferential treatment of less developed countries, and of membership in trade blocs.
