Calibrating estimation tools for software development
Software Engineering Journal, 1990Desired improvement in the software process and product has given rise to greater use of quantitative managment techniques in software development. The use of algorithmic-based software cost estimation tools has been a part of this movement. This paper uses data collected from six commercial organisations on 112 software projects to investigate the ...

WindSat calibration and geophysical parameter estimation
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004Three aspects of WindSat performance are presented. (1). End-to-end system calibration is tested by comparisons between WindSat measurements and a robust model of the Earth TB using the vicarious cold reference method. (2). In an effort to determine probable causes for any calibration biases or scale errors that are identified, a refined Antenna ...

Estimating the intervention effect in calibration substudies
Statistics in Medicine, 2019Exposure assessment is often subject to measurement errors. We consider here the analysis of studies aimed at reducing exposure to potential health hazards, in which exposure is the outcome variable. In these studies, the intervention effect may be estimated using either biomarkers or self‐report data, but it is not common to combine these measures of ...

Realtime gaze estimation with online calibration
2014 IEEE International Conference on Multimedia and Expo (ICME), 2014For an eye gaze estimation system, calibration is an unavoidable procedure to determine certain person-specific parameters, either explicitly or implicitly. Although several offline implicit calibration methods have been proposed to ease the calibration burden, the calibration procedure is still cumbersome and the gaze estimation accuracy needs further

Regresyon tahmin yöntemine benzeyen bir diğer tahmin yöntemi de ayarlama tahmin edicisi yöntemidir. Ayarlama tahmin edicisi yardımcı değişken(ler) bilgisini tahminlerin etkinliğini arttırmak için kullanır. Ayarlama tahmin edicisi, bir veya birden çok yardımcı değişken (x değişkenleri) için yığın toplamlarını bilmeyi gerektirir.

Bayesian calibration for forensic age estimation
Statistics in Medicine, 2015Forensic medicine is increasingly called upon to assess the age of individuals. Forensic age estimation is mostly required in relation to illegal immigration and identification of bodies or skeletal remains. A variety of age estimation methods are based on dental samples and use of regression models, where the age of an individual is predicted by ...

Calibration as parameter estimation in sensor networks
Proceedings of the 1st ACM international workshop on Wireless sensor networks and applications, 2002We describe an ad-hoc localization system for sensor networks and explain why traditional calibration methods are inadequate for this system. Building upon previous work, we frame calibration as a parameter estimation problem; we parameterize each device and choose the values of those parameters that optimize the overall system performance. This method

Issues in calibrating effort estimation models
ACM SIGSOFT Software Engineering Notes, 1999This paper discusses some important issues when calibrating, or developing effort estimation models for software projects. The author has developed and calibrated several effort estimation models within Nokia Corporation. The paper takes use of the experience gained in those situations.

On the estimation of variance of calibrated estimators of the population covariance [PDF]
, 2007 The problem of variance estimation of the calibrated estimators of the finite population covariance is considered. The calibrated estimators of the population covariance are more efficient compared to the straight estimators provided the auxiliary variables are well correlated with the study variables.
