The other regression analyses were performed using R, version 2.15.2 (http://www.r-project.org/).org/
Residuals of this and all other regression analyses were checked for patterns e.g. of heteroscedasticity, normality or highly influential data points using diagnostic plots (see additional file 3: diagnostic plots).
We tested whether nocturnal fish have larger eyes than diurnal species by Standardised Major Axis regression of eye diameter and body mass, performed with the R package smatr (as for all other regression analyses) [ 40].
Logistic regression analysis and other linear regression analyses were used to evaluate associations between patients' demographics and outcomes.
Analysis was conducted using SAS version 9.2 (SAS Institute, Inc., Cary, NC, USA) for analytic dataset construction, descriptive statistics, and logistic regression; while Stata SE version 11 (StataCorp LP, CollegeStation, TX, USA) was used for other multiple regression analyses.
Resource items were grouped in seven categories: general ward nursing, nursing on ICU, clinical chemistry laboratory tests, microbiology exams, radiology exams, medication drugs, and other.linear regression analyses were conducted to identify variables predicting costs of hospitalisation for CAP.
After adjustment for baseline CORT and other covariates, regression analyses did not reveal significant associations of BPb or TPb with the CORT response to the stressor except in one condition; 15 min after baseline, participants with higher TPb levels had higher CORT levels (Table 3).
On the other hand, multiple regression analyses shown in table 3 indicated that other types of substitution rates were negatively correlated to the GC content but the correlation was not significant.
26 Furthermore, alternative strategies for constructing risk models other than simple regression analyses are being explored, and these may add increased complexity to the reporting.
