Sentence examples for a baseline function of from inspiring English sources

The limitation of the DPM loss-of-function phenotype to nighttime sleep implies there is a baseline function of DPM activity that occurs even in isolated animals in a relatively stimulus-poor environment, but the small magnitude of these changes suggests that DPMs are not the major driver of baseline sleep.

Establishing 'reference sites' is a difficult task and a critical factor in determining the baseline functioning of ecosystems.

For creating the compound covariate, one first fits the univariate Cox regression model for each individual gene, that is, (1) h t | x k = h 0 k t exp x k β k, k = 1, 2, …, p where h0 k (t) is a baseline hazard function of each gene k, and β k is a corresponding parameter to be estimated.

The most popular class of survival models is the class of proportional hazard models [1,2], where the hazard of an individual at time t is described as the product of the baseline function and of a positive term which is an exponential function of a vector of covariates w′ multiplied by vector of regression parameters θ.

We thus calculated an estimate of baseline function by use of the MDRD equation as recommended by the ADQI group [ 24].

Instead, we calculated an estimate of baseline function using the Modification of Diet in Renal Disease equation, as recommended (assuming a lower limit of the normal baseline glomerular filtration rate of 75 ml/min) and previously applied [ 2, 4, 9].

The hazard function is described as the product of a baseline hazard function and a positive (exponential) function of possibly time-dependent fixed and random covariates.

Proportional hazard models and their extension to include random effects describe the hazard function of each individual λ(t) (i.e., its limiting probability of dying at time t, given it is still alive just prior to t) as the product of a baseline hazard function and a positive (exponential) function of explanatory covariates.

Erectile function was poorly reported, possibly as a result of poor baseline function.

Quantitative PCR data were analysed using the Sequence Detection Software version 1.4 program (Applied Biosystems) with the Auto baseline function and a threshold of 0.05.

All community-dwelling residents aged 65 and over and without functional decline (n = 1560), of Omishima town, Japan, were assessed in 1996 using a simple illustrative measure, "the Typology of the Aged with Illustrations" to establish a baseline level of function and were followed annually until 2002.
