What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Good so far; expensive, however, AND when I agreed to your discounted one year offer when I intended to cancel after one month, I didn't realize the sum offered was in addition to the $20 one month fee, so it didn't turn out to be such a great deal after all. I was canceling, because I honestly don't see myself using this much more if even ever again. However, for the discounted rate (WITHOUT the $20 added in), I thought 'why not?' I am going to evaluate over the next couple weeks to see if I really DO want to continue a subscription, discount or otherwise.

I was able to type in all my information & save the forms. I did find entering the data to be cumbersome as I had to move the data to the correct spot on the form.

Great
Easy to use the program, has a lot of great features & tools to use within the program. Will recommend to others. Love the timeline status for documents sent out or waiting to be signed
Don't like the reloading that the program does when open reopening documents sometimes. Overall not much to complaint about

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.)

It's early, but I like the versatility, and I found it a useful solution while updating my existing resume. I need to continue to use it, though. Need some experience still.

The reason it is a four instead of a five...
The reason it is a four instead of a five is I feel like there is a strong learning curve... at least for me.
So I am still learning.
Check back with me in a month and let's see if we can delete this 4 rating and move it up to a 5!!

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?
enter the number, press the inverse (in) or shift button, then. Press the log (or LN) button. It might also be labeled the 10x (or ex) button.

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.
