## #StackBounty: #pdftex #pdf How to create a fillable PDF file with many identical-looking but distinct boxes

### Bounty: 50

I want to make a document with dozens of identical looking boxes (as in first name, last name) that will be filled with different text.

If I copy/paste my code to generate the boxes then the resulting PDF will have the property that once a box is typed-in the other boxes will fill with the same entry.

Is there a quick/smart way of doing this task?

`````` documentclass{paper}
usepackage{hyperref}
begin{document}
begin{Form}[action=mailto:me@univ.edu?subject={The form},method=post]
TextField[width=5cm, height=0.6cm]{Type Last Name}
vskip .1in
TextField[width=5cm, height=0.6cm]{Type First Name}
vskip .1in
TextField[width=5cm, height=0.6cm]{Type Last Name}
vskip .1in
TextField[width=5cm, height=0.6cm]{Type First Name}
vskip .1in
end{Form}
end{document}

## #StackBounty: #linux #command-line #pdf scale pdf to exact size

### Bounty: 350

I need a program for Linux which can scale pdf files to a specified size, stretching them if needed. I would prefer a command line program, but something with a gui is ok too.

I found a lot of programs to scale the pdf, but they all scale proportionally, and then just add a white border. But I need something which will stretch the pdf file, so it has the exact needed size without white border.

I know stretching may make the pdf look odd, but I have some pdf files which just need to be a 1.5 mm higher, so it is less then 1% I need to stretch them, so I still think it will look ok.

## #StackBounty: #distributions #logistic #normal-distribution #pdf #model Relationship between a logistic decision function and Gaussian …

### Bounty: 50

Imagine an experiment, in which an observer has to discriminate between two stimulus categories at different contrast levels $$|x|$$. As $$|x|$$ becomes lower, the observer will be more prone to making perceptual mistakes. The stimulus category is coded in the sign of $$x$$. I’m interested in the relationship between two different ways of modeling the observer’s "perceptual noise" based on their choices in a series of stimulus presentations.

The first way would be to fit a logistic function

$$p_1(x) = frac{1}{1+e^{-betacdot x}}$$

where $$p_1(x)$$ is the probability to choose the stimulus category with positive signs ($$S^+$$). Here, $$beta$$ would reflect the degree of perceptual noise.

A second way would be to assume that the observer has Gaussian Noise $$mathcal{N}(0,sigma)$$ around each observation of $$x$$ and then compute the probability to choose $$S^+$$ by means of the cumulative probability density function as follows:

$$p_2(x) = frac{1}{sigmasqrt{2pi}}intlimits_{z=0}^{infty}e^{-frac{(z-x)^2}{2sigma^2}}$$

In this case, $$sigma$$ would be an estimate of the perceptual noise.

I have a hunch that both these approaches are intimately related, but I’m not sure how. Is it an underlying assumption of the logistic function that the noise is normally distributed? Is there a formula that describes the relationship between $$beta$$ of $$p_1(x)$$ and $$sigma$$ of $$p_2(x)$$? Are, in the end, $$p_1(x)$$ and $$p_2(x)$$ essentially identical and could $$p_1$$ be derived from $$p_2$$?

## #StackBounty: #pdf Why isn't the 'Map Colors' fixup changing text colors?

### Bounty: 50

I saw this question some where, I think Reddit, but I can’t find it. I have same issue.
Please see the screenshot beneath. I’ve uploaded the PDF to mega.nz I’m using Adobe Acrobat Pro DC Version 2019.010.20064.

I’m trying to convert the book’s default (C, M, Y, K) = (99%, 98%, 18%, 6%) (ie dark purple) to (90, 0, 90, 0) (green). After I click ‘OK’ and click ‘Fix’, Adobe Acrobat executes the fixup, but the color fails to change. Why?
