Today, banks are increasingly using software to decide who will get a loan, courts to judge who should be denied bail, and hospitals to choose treatments for patients. These uses of software make it c...
A study comparing acceptance rates of contributions from men and women in an open-source software community finds that, overall, women’s contributions tend to be accepted more often than men’s – but w...
Bias-Variance Tradeoffs in Program Analysis
Program Analysis Machine Learning Verification
<
2016/5/24
It is often the case that increasing the precision of a program analysis leads to worse results. It is our thesis that this phenomenon is the result of fundamental limits on the ability to use precise...
Investigation of Elevation Bias of The SRTM C-And X-Band Digital Elevation Models
Remote Sensing Vegetation Retrieval Multifrequency DEM/DTM SAR Land Cover
<
2015/11/20
The paper presents results of a comparative study of the vegetation-caused elevation bias of the space shuttle topographic mission data product, both C- and X-band (SRTM.C/X). The SRTM.C/X bands data ...
CALIBRATING AREA ESTIMATE BIAS ON CATEGORICAL MAPS USING THE CONTINGENCY TABLE
Categorical map Area estimation Quantitative error Sampling Contingency table Calibration model

This paper presents and compares approaches of estimating true area on the ground and calibrating quantitative errors of area estimate on categorical maps from the contingency table. Results directly ...
Bias Reduction for Dynamic Nonlinear Panel Models with Fixed Effects
Fixed Eff ects Dynamic Nonlinear Panel Models
<
2015/9/22
The fixed effects estimator of panel models can be severely biased because of well-known incidental parameter
problems. It is shown that this bias can be reduced as T grows with n. We con...
Higher Order Properties of Bootstrap and Jackknife Bias Corrected Maximum Likelihood Estimators
Bootstrap and Jackknife Bias Likelihood Estimators
<
2015/9/22
Pfanzagl and Wefelmeyer (1978) show that bias corrected ML estimators are higher order efficient.
Their procedure however is computationally complicated because it requires integrating complicat...
Estimation with Weak Instruments: Accuracy of Higher Order Bias and MSE Approximations
weak instruments higher order expansions
<
2015/9/22
In this paper we consider parameter estimation in a linear simultaneous equations model. It
is well known that two stage least squares (2SLS) estimators may perform poorly when the
instruments are w...
SENSOR ORIENTATION FOR HIGH-RESOLUTION SATELLITE IMAGERY: FURTHER INSIGHTS INTO BIAS-COMPENSATED RPCs

2013/7/24
We propose an image conspicuity index that combines three factors: spatial dissimilarity, spatial distance andentral bias. The dissimilarity between image patches is evaluatedin a reduced dimensional ...
A W-Band Photonic Transmitter-Mixer Based on High-Power Near-Ballistic Uni-Traveling-Carrier Photodiodes for BPSK and QPSK Data Transmission Under Bias Modulation
Photonic QPSK Data Abstract
