A Probability Model for Census Adjustment

The census can be adjusted using capture-recapture techniques: capture in the census, recapture in a special Post Enumeration Survey (PES) done after the census. The population is estimated using the Dual System Estimator (DSE). Estimates are made separately for demographic groups called post strata; adjustment factors are then applied to these demographic groups within small geographic areas. ...

An Adaptive Self-adjusting Bandwidth Bandpass Filter without IIR Bias

In this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. This adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. In addition, an important feature of the proposed structure is that the conventional bias existing ...

Methods for Census 2000 and Statistical Adjustments

This article outlines procedures for taking the US census, making adjustments, and evaluating the results. The census turns out to be remarkably accurate. Statistical adjustment is unlikely to improve on the census, because adjustment can easily put in more error than it takes out. Indeed, error rates in the adjustment are comparable to if not larger than errors in the census. The data suggest ...
