I am more than impressed with PDFfiller...Beyond my expectations! Very user friendly, and it is cutting my time spent in half..Thanks for a great product

I believe the staff is dedicated to helping the customers and are very professional. Thought I might have to talk to them in person, but they answer and respond quickly through chat and do everything they can to help you right away. When I just had to get my material out right away and short on funds allowed me to try out the program just a few days after I explained my difficulty. Then after few days able to of course, pay for this program that has helped me so much. The forms are easier to read by using PDFfiller, and the video of how to work the software is helpful as well. The people are just awesome!! Very helpful and respond immediately. I would recommend this to friends and family as well.

I am very impressed at the features, especially being able to combine pdf files and edit files. I find navigating to and from the 'My Forms' area a bit clunky. The 'save as' feature takes forever to achieve, too many steps for a file that is already created. For my business, it would be a huge benefit to be able to print out a confirmation page when my faxes have been sent and received. I like to keep such confirmations with the files as proof. All in all, I love the program and am thankful for such a convenient and manageable product.

I was surprised I still have to hand write a form to send to IRS - I thought this would take care of it for me. Or did I miss something.

Easy PDF
PDF filler is undoubtedly among the best software I have used for manipulating PDF documents. Easy to use, it offers many features and is less expensive than other software competitors. The only real flaw in my opinion is the lack of clarity about the free trial. The user can modify his document and only when downloading it he is asked to register with a payment method. This can be confusing and irritating if you don't know it beforehand.
easy to use
accessible from anywhere
includes many features
there are often problems with payments
there is no clarity on the 30-day free trial

How do you back transform a log?
For the log transformation, you would back-transform by raising 10 to the power of your number. For example, the log transformed data above has a mean of 1.044 and a 95% confidence interval of ±0.344 log-transformed fish. The back-transformed mean would be 101.044=11.1 fish.
How do you reverse a log transformation in R?
reciprocal. In this case the inverse of log(x) is 1/log(x) inverse function. In this case it refers to solving the equation log(y) = x for y in which case the inverse transformation is exp(x) assuming the log is base e. (In general, the solution is box if the log is of base b.
What is the inverse of log2?
To find the inverse of f(x) = log2(x + 2) + 2 we write y = log2(x +2)+2, change variables (to indicate that we are swapping inputs and outputs) x = log2(y +2)+2, and subtract 2 from both sides x 2 = log2(y + 2).
How do I Unclog a number?

How do you reverse a log in Excel?
To calculate the inverse log of a number in the first two cases, raise the base to the power of the value returned by the particular logarithm function being used. To find the inverse natural log, use the EXP function.
Why do we do log transformation?
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.
Why do we transform data?
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.
