We present a method for estimating reproduction numbers for adults and children from daily onset data, using pandemic influenza A(H1N1) data as a case study. We investigate the impact of different ...

Estimating means making numbers simpler but keeping their value close to what it was. The result is not exact, but it gives an idea of what the total will be. There are steps which can be followed to ...

IN ecological work it is often necessary to have comparative estimates of the numbers of organisms in a large number of samples. An exact valuation may not be required, but an approximate numerical ...

Only a few countries have official population statistics which are sufficiently accurate to produce reliable estimates of death rates at high ages. For other countries, there are several methods which ...

This paper presents the results of a study with two main objectives: (1) to investigate an extension of some principles recently developed in the theory of cluster sampling, and (2) to determine the ...

Abstract: This paper describes an estimating system of human numbers for resolution change by a thermal array sensor. In this system, the sensor is attached to ceiling of a room and acquires ...
