In addition, these models were used to assess the within-household consistency of household usage frequency relative to other households.
Population-wide temporal variation and within-household consistency were examined both within telephone surveys and within web surveys, and quantified using Generalized Estimating Equations and Mixed Effect Modeling.
Kendall's ICCs, used for evaluating within-household consistency, were high for professional application (ICC = 0.77) and pet treatment (ICC = 0.66), but relatively low for self-application of outdoor (ICC = 0.30) and indoor sprays (ICC = 0.20).
Mixed-effects models for the rank-transformed pesticide use frequencies allow us to assess population-wide interview wave effects and season effects as well as within-household consistency (Table 5).
We then used Kendall's intraclass correlation coefficients (ICC) of the rank-transformed variables to characterize within-household consistency and computed as the ratio of the between-household residual variance component to the sum of the between-household and within-household residual variance components [ 32, 33].
The neighborhood method also assumes respondents have the ability to report on events within their own households and in all neighboring households with equal consistency and that any hostile or difficult relationships between households or household members would not bias accurate reporting.
A number of household factors showed consistency as predictors of endotoxin across sampling locations.
The following are five suggestions on how to provide consistency from household to household for the sake of the children.
The Friedman Test and Kendall's W Test [ 72, 73], two non-parametric techniques, were used to assess the consistency of household food supplies across multiple observations.
Due to the small sample size of the pilot data, the Friedman Test and Kendall's W were used to assess the consistency of household food supplies across multiple observations.
Time-sharing agreements requiring an exchange of the "children" at 7 00 p.m. on a Friday night may seem a bit absurd, when your 16-year-old is heading out the door with friends at 6 30 p.m.! Whenever possible, try to establish aligned goals and expectations with each other, so that your children maintain consistency between households.
