[julia-users] How to use weight in the data.

[paul analyst]

How to use weight in the data. Often in social research data are used in 
weight. It is one variable (column) indicates how much a given row in the 
data set is weighed (average weight = 1). Typical weights are numbers in 
the range 0.01 - 10.0 but can be any positive numbers. Sums, averages, and 
other 
basic statistics of the use of weight is not difficult to Julia. But how to 
prepare/compute a set of weighted counting any statistics, correlation, 
algebraic transformations, etc.
