Rock House will ply vacationers with such luxurious inducements as a sparkling infinity pool surveying the breathtaking blue waters of the Turks.
We did not pool surveys for a given plot within a year because multiple surveys within a year were rare and incomplete, and because of high species turnover across seasons (see Text S1, Figure S2).
Several studies have been conducted including questionnaires and interviews to physicians [ 16- 18], questionnaires to the elderly [ 19], and brief nationwide pool surveys, although only having consisted of a few straightforward questions [ 20, 21].
I've developed a statistical model for pooling survey results, taking into account (1) estimates of voting intentions based on earlier polling, (2) the track record of each pollster, when known, (3) the different sample sizes used by each pollster.
Estimated yearly coral cover loss based on annually pooled survey data was approximately 1% over the last twenty years and 2% between 1997 and 2003 (or 3,168 km2 per year).
We analyzed data from 3,348 participants of the National Health and Nutrition Examination Survey NHANESS) 2003 2004 and 2009 2010 pooled survey cycles.
Because providers may or may not take part in all of the surveys, 24 out of the 255 respondents participated in more than one survey during the pooled survey periods, with 21 completing two and three participating in all three.
In adjusted models for the pooled survey sample, odds ratios (aORs) for a negative VZV IgG result in association with 1-unit increases in ln-TUA1 and ln-TUA2 were 1.87 (95% CI: 1.03, 3.44) and 1.40 (95% CI: 1.0, 1.97), respectively (Table 3).
After controlling for the expansion in improved water supply access over the study period through the pooled survey data analysis, household perceptions of drinking water safety appear stable over time, although small changes in perceptions would be difficult to detect because of survey sampling errors.
