What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I like it- does what it says- easy to fill in a form. My local authorities keep changing their forms so everytime we spend a long time converting them to word files for editing, they become obsolete! Now, we just work with this weeks form and it doesn't matter if they change the layout! Perfect- no more time wasting with forms!

Using iPhone to complete apps and send out for signature.. Had some glitches.. Wasn't able to select or choose (full access or sign only option for recipients. The screen shut down too quickly each time and 'disappeared before I could actually select.

It worked great in a pinch, but given the cost and how often you may or may not need something like this, I wonder if it'd be cheaper to buy a program to use rather than to keep this going on a monthly basis. I think it really depends on your individual needs. Though, when I needed something typed and there was no fillable version, this site was a lifesaver!

I love it I love it! I am a teacher and due to COVID-19, I have had to learn how to teach online. This program allows me to give feedback directly on the page for each student, as well as create and personalize assignments. It's been a lifesaver!

Took me a minute to get the hang of… Took me a minute to get the hang of it... after that no problem. Not sure if there is a tutorial for typing in text and moving the text where you need it...

PDFfiller is the best app ive found so far for editing and creating fillable forms. I've tried one which is very inferior to it. Definetly gets the job done. Would recommend to anyone.

Great software Great software! Very easy to use and does just about everything you would want a PDF editor to do. The only issue I had was when replacing text the text box deleted the line the text was sitting on and I ended up with a break in the line. Other than that I highly recommend!

The log transformation can be used to make highly skewed distributions less skewed. This can be valuable both for making patterns in the data more interpretable and for helping to meet the assumptions of inferential statistics. Figure 1 shows an example of how a log transformation can make patterns more visible.
Transforms are usually applied so that the data appear to more closely meet the assumptions of a statistical inference procedure that is to be applied, or to improve the interpretability or appearance of graphs. Nearly always, the function that is used to transform the data is invertible, and generally is continuous.
1 Answer. Log transformation leads to a normal distribution only for log-normal distributions. Not all distributions are log-normal, meaning they will not become normal after the log transformation.
If you use natural log values for your dependent variable (Y) and keep your independent variables (X) in their original scale, the econometric specification is called a log-linear model. These models are typically used when you think the variables may have an exponential growth relationship.
square-root for moderate skew: sort(x) for positively skewed data, log for greater skew: log10(x) for positively skewed data, inverse for severe skew: 1/x for positively skewed data. Linearity and heteroscedasticity:
To standardize your data, i.e., data with a mean of 0 and a standard deviation of 1, you can use the scale function from the base package which is a generic function whose default method centers and/or scales the columns of a numeric matrix.
R log Function. Log() function computes natural logarithms (Ln) for a number or vector. Log10 computes common logarithms (Lg). Log2 computes binary logarithms (Log2).
Log transformation The value 1 is added to each of the pixel value of the input image because if there is a pixel intensity of 0 in the image, then log (0) is equal to infinity. During log transformation, the dark pixels in an image are expanded as compare to the higher pixel values.
