### Predicting values in a given range [0, 1] (not probability) [duplicate]

I need to predict the impact of a set of node failures in a network, based on 2 features: the fraction of failed nodes and a measure of their network centrality. Failure of less important nodes will ...

### Which regression model to use for a probability as dependent variable? [duplicate]

My dependent variable is a probability. As such, values lie between 0 and 1. The most common values are 0, 0.5, and 1 each occurring in 20% to 30% of the observations but any value in between is ...

### Method to predict outcome as percentage of two categories? [duplicate]

In real world example I have elemental composition data for groundwater, which is known to be coming from two sources. I have control data where all predictors are from source A and data where all ...

### How to build a model with a continuous response variable bounded from 0 to 1? [duplicate]

How to build a regression model with a continuous response variable bounded from 0 to 1? I think it is not logistic regression, where I am not predicting a binary response variable, Right? Sorry ...

### How small a quantity should be added to x to avoid taking the log of zero?

I have analysed my data as they are. Now I want to look at my analyses after taking the log of all variables. Many variables contain many zeros. Therefore I add a small quantity to avoid taking the ...

### How to do logistic regression in R when outcome is fractional (a ratio of two counts)?

I'm reviewing a paper which has the following biological experiment. A device is used to expose cells to varying amounts of fluid shear stress. As greater shear stress is applied to the cells, more of ...

### Is it technically “valid” to fit a logistic regression with a dependent variable that is a proportion?

Several posts (here and here) suggest that beta regression is more appropriate when the dependent variable is naturally bounded between 0 and 1. My question is, leaving appropriateness aside, is it ...
