Sentence examples for using a logistic function from inspiring English sources
Using a logistic function allows us to define a maximal contribution for a given feature (functional type), thus a point cannot be dominated by any single chemical group.
To compute the predicted MOS (tilde {M}), a regression analysis on each objective metric results O was performed using a logistic function as a regression model: tilde{M} = a + frac{b}{1+expleft -c cdot (O - d)right)} (2).
In this study logistic regression is used to estimate the correlation between the dependent variable (occurrence of debris flow) and independent variables (influencing attributes) by evaluating probabilities using a logistic function.
FA assembly rate was modeled using a logistic function (exponential growth at early time points which plateaus to a maximum) and the final continuous phase of FA disassembly was modeled as simple exponential decay.
The probability of death was simultaneously modeled using a logistic function [ 14, 15].
The distances between Cα are translated into contact probabilities using a logistic function.
Papke and Wooldridge (1996) used a logistic function for G y, x′) in the framework of generalized linear models (GLM) [that is, ( Gleft( y,{x}^{prime}right)=frac{ exp left( y,{x}^{prime}right)}{1+ exp left( y,{x}^{prime}right)} )] which was extensively discussed in their paper.

We developed a regional-scale succession model based on empirical information on fire return intervals, fire sizes (using a reverse Weibull function) and post-fire successional trends (using a logistic growth function), based on an extensive dataset collected in a 65,000 km2 section of the boreal forest located in eastern Quebec.
