What do you like best?
Ease of use! Very intuitive program that does NOT require a lot of training to use.
What do you dislike?
I use the program infrequently in my present roll, so was surprised by the page lay-out change. It was a bit more difficult to simply pick it up and understand the new format.
What problems are you solving with the product? What benefits have you realized?
I use PDFfiller for city and county land-use applications. Having the ability to complete these varying forms simply, and have them stored for future use is invaluable!

Good PDF App Although I found out that I didn't need a pdf app, it was a pleasant experience, and the free trial served its purpose of discovering if it was for me.

Good value for price When using the offer for roughly 40€ per year, PDF filler is a no-brainer when you need to fill in several forms a year for your household / family (e.g. insurances, real estate, etc.)

Excellent Service I did the 30 day trial period and was very satisfied with the process.I used the product for about 10 different documents within a 2 day period. I forgot about the trial period and was charged for an annual subscription and was emailed the confirmation. I went online and requested to cancel the subscription due to not needing the product and received the cancellation with 5 minutes, very satisfied.

Support is good but last release is bad I am really fond of their support team. They are very friendly and provide all help the can. But that's not enough for good product. Support can't fix bugs or make it good for tablets. Try harder.

Great features. Easy to learn. The features I've used so far have been fantastic. pdfFiller is quick and easy to learn. The only feature it doesn't have that I would utilise is when creating a form and using the 'formula' option I'd like to be able to add formulas like in excel e.g. =field_1 so that I can duplicate a form entry where it has been entered previously. I chatted with the live support team about this and they were fast to respond & took this request onboard for future updates. A great product and fantastic customer service.

I would only add that when adding text to the editor, it can be moved without blocking the height. Sometimes the PDF blocks the location of the text and it is difficult to align it with the original text.

How does a log transformation work?

The log transformation is, arguably, the most popular among the different types of transformations used to transform skewed data to approximately conform to normality. If the original data follows a log-normal distribution or approximately so, then the log-transformed data follows a normal or near normal distribution.

What does a log transformation do?

Log Transformations. 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.

What are log transformed variables?

A typical use of a logarithmic transformation variable is to pull outlying data from a positively skewed distribution closer to the bulk of the data in a quest to have the variable be normally distributed.

What happens if log transformation does not normalize data?

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.

What is natural log transformation?

In log transformation you use natural logs of the values of the variable in your analyses, rather than the original raw values. Log transformation works for data where you can see that the residuals get bigger for bigger values of the dependent variable.
