Inflation Rates are Very Different When Housing Rents are Accurately Measured

Are Abnormal Yolk Sac Characteristics Important Factors in Abortion Rates?

How Interest Sensitive is Investment? Very (when the data are well measured)

We use a unique data set covering over 30,000 Italian firms over 10 years to estimate the interest sensitivity of investment. This data set has three special attributes. First, it includes information that allows us to link firms to the banks from which they are borrowing. Second, the terms of the lending agreements are quite accurately recorded. Finally, we have balance sheet and other cost in...

SVM Ensembles Are Better When Different Kernel Types Are Combined

Support Vector Machines (SVM) are strong classifiers, but large data sets might lead to prohibitively long computation times and high memory requirements. SVM ensembles, where each single SVM sees only a fraction of the data, can be an approach to overcome this barrier. In continuation of related work in this field we construct SVM ensembles with Bagging and Boosting. As a new idea we analyze S...

141 Bovine Embryo Development Rates Are Affected When Oocytes Are Matured in Different Vials Containing Hepes/bicarbonate Buffered Medium.

Laboratory ware for the in vitro-produced embryos is generally made from embryo-tested plastic instead of glass. The quality of the plastic is crucial for the outcome because plastic is often toxic to gametes (Nijs et al. 2009 Fertil. Steril. 92, 527-535). In addition, gas molecules permeate through the plastic at a rate that depends on a variety of factors, such as diffusion coefficient and th...

Exact, Nonparametric Inference When Doses Are Measured With Random Errors

Studies that estimate the effects of exposure to a possibly harmful agent often compare exposed subjects who received varied doses with matched controls who received zero dose. If the doses are measured with error, then one may wish to use the fallible doses to estimate a linear relationship between the unobserved true dose and the observed response. If one is willing to assume that the dose er...
