Association of FCGR haplotypes with GCA was investigated further using the haplotype trend regression approach proposed by Zaykin and colleagues [ 34] for dealing with uncertain phase.
Association of FCGR3A FCGR3B haplotypes with RA was investigated further using the haplotype trend regression (HTR) approach proposed by Zaykin and coworkers [ 33] for dealing with uncertain phase.
In this study the accuracy is evaluated by comparison with the global Terra MODIS NDVI (MOD13C2 Collection 5) data using linear regression trend analysis.
We analyzed trends in mortality using joinpoint regression analysis using the Joinpoint Regression Program, Version 4.1.1 [ 20, 21].
The influence of these factors on wear rate of AA6061/AlNp composite was analyzed using the developed regression model and predicted trends were discussed with the aid of worn surface morphologies.
By using the linear regression test to test for trend, competence was not significantly correlated with increasing penicillin resistance among isolates belonging to serotypes 6B, 14, 19F, 9V, and 23F (p = 0.7 for CSP-1, p = 0.3 for CSP-2).
Survival curves of the three groups were estimated by the Kaplan Meier method and compared using the Cox regression model assuming an ordered trend for the three groups as previously described (Cheng et al., 2013, Shedden et al., 2008) and the log-rank test was used to compare the overall survival curves among three groups.
Implementing the regressive model using the support vector regression algorithm on the trend component of the time series.
Using the multivariate Cox regression model, this trend turned out to be more distinct (HR: 1.73; 95% CI: 0.96 3.13, Cox P=0.068).
It's also why when you switch to "less smoothing" -- which uses the loess regression -- the trend might actually look smoother than the default model.
