Until now, most microtargeting was based on backward-looking data — the car someone bought or the magazines they subscribed to, says Cyrus Krohn, a co-founder of CrowdVerb.
The variables significantly associated with the outcome on analysis (P ≤ 0.2) were included in the multivariable analysis by applying a multiple logistic regression based on backward elimination of data.
Both methods yielded the same result and therefore only results based on backward elimination are presented.
For this procedure we retained variables based on backward elimination, p < 0.1.
Given this poor success, it may be easier to utilise an empirical backward looking, "data mining" or "brute force" approach.
Model selection was done based on backward selection and ANOVA tests.
The final model (third column) is based on backward elimination of non-significant factors.
"Digital preservation is based on constantly looking after the data".
Based on the preliminary data, it looks as if there are numerous suitable planets.
As a result, this ballerina with her head screwed on backward looked grotesquely comic.
A recent study based on 2005 2006 NHANES data took a preliminary look at potential sources of BPA exposure.
