Loving it so far. Wish the search for documents in their library was easier to find, but other than that, I've been very happy with ease and quality.

What do you like best?
Huge time saver because we spend a great deal of time filling out forms, and we fill out the same forms with the same info year after year, and pdffiller keeps it for us and all we have to do is change the date.
What do you dislike?
Nothing really. It's an odd process, fill in your forms, hit this button, then hit that button, and then go find the finished product in your downloads. I would prefer to specify where it goes and rename it before it goes there.
Recommendations to others considering the product:
If you are an insurance agent that uses Acord forms, this is for you.
What problems are you solving with the product? What benefits have you realized?
This definitely saves me money because it save my staff huge amounts of time. Everything is now done digitally, so we need our forms in a digital format that we can save from year to year and change information in the forms at will.

Simple tool that increases productivity in office
I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office.
My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed.
I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

I have really enjoyed using the software. I use it on my iPhone, on my windows PC, on my Mac and my iPad so it's a multiplatform Holy Grail. I still use the program. Have it installed on all my computers and IOS devices. there are a lot of features that I've not used so I can't truly say much about them, but overall I'd definitely recommend the program to others.

How do you show that a statistic is complete?
Definition: A statistic T is called complete if E[g(T)]=0 for all and some function g implies that P(g(T)=0)=1 for all.
How do you calculate sufficient statistics?
It is easy to see that if f(t) is a one to one function and T is a sufficient statistic, then f(T) is a sufficient statistic. In particular, we can multiply a sufficient statistic by a nonzero constant and get another sufficient statistic.
How do you read a sufficient statistic?
Sufficiency pertains to data reduction, not merely estimation. A sufficient statistic need not estimate anything. For example, if X1,In are did samples drawn from an exponential distribution with unknown mean, then X is sufficient for, but so is (X1++Xn1,In).
Are the calculated means sufficient in explaining the data?
x is a sufficient statistic if it retains all the information about the population mean that was contained in the original data points. According to statistician Ronald Fisher, no other statistic that can be calculated from the same sample provides any additional information as to the value of the parameter.
How do you find minimal sufficient statistics?
A sufficient statistic T : X T is minimal sufficient if for any sufficient statistic U : X U there is a measurable function g : UT such that T = g(U) ex|(· |)-a.s. for all .
What is the distribution of the sufficient statistic?
In particular, a statistic is sufficient for a family of probability distributions if the sample from which it is calculated gives no additional information than does the statistic, as to which of those probability distributions is that of the population from which the sample was taken.
Is sufficient statistic unique?
The minimal sufficient statistic is not unique. But, the minimal sufficient partition is unique. {1+(yo )2}. The ratio is a constant function of if T(Y n)=(Y(1), ×··, Y(n)).
Is minimal sufficient statistic unique?
If both T and S are minimal sufficient statistics, then by definition there is a one-to-one function such that T = (S). Hence, the minimal sufficient statistic is unique in the sense that two statistics that are functions of each other can be treated as one statistic.
