A few tools are available for finding differentially expressed genes under varying conditions among which statistical methods are widely accepted, including methods based on t-test and SAM [ 4, 5].
So great was the variation in results that the panel conducted an exercise by varying the assumptions and statistical methods underlying these studies, using the same data sets; estimates of overdiagnosis rates were found to vary across the range of 0 36% of invasive breast cancers diagnosed during the screening period.
With work status as a time-varying confounder, standard statistical methods will not be adequate to estimate an unbiased effect of the exposure on the outcome when work status is also affected by prior exposure.
The versatile approach can be used to simulate a great variety of data with varying properties in order to compare statistical methods.
This seems to be the case if we examine the Na, K, Ca and SO3 contents listed in Tables 1 and 2. When considering a large number of the minerals, it requires statistical methods to assign varying degrees of significance to the differences.
The current study adds to published literature by including significant numbers of methicillin-resistant isolates and by using statistical methods appropriate for varying time at risk.
The effectiveness of emergency medical interventions can be best evaluated using time-to-event statistical methods with time-varying covariates (TVC), but this approach is complicated by uncertainty about the actual times of death.
To account for this immortal time, the analysis should consider the users of metformin as unexposed until they actually receive their first metformin prescription and use statistical methods for time-varying exposures.
We have employed differential principal analysis to develop statistical methods for estimation of location-varying coefficients of the ODE.
We use differential principal analysis to develop statistical methods for estimation of location-varying coefficients of the ODE.
