After discovering that TurboTax does not have a Mac version for business tax returns, I found PDFfiller and it is a great alternative. It is much more reasonable and includes all the forms needed to file my return.

It has made work much easier. In the legal field we deal with a ridiculous amount of documents. Many IRS and government forms require some PDF filler, Adobe Acrobat does not do the job PDF filler can. To be able to access my docs from anywhere is amazing. The email, sign, fax, and all the other features make it actually fun.

I liked that I can type in the blanks for documents , but I only needed it once and I didn't really didn't understand the price I though got it was $6 a month not $72. But the understanding of customer service was great I'm glad I'll be getting my refund. Thank you again. It's a ok service maybe for a business not personal use

Great customer service support
Great customer service support. They have always been responsive on a timely manner when I need help. I use them to submit 1099 forms to the IRS. They even developed a 'fix' to their form so that I could submit a form for an employee that lives out of the country.

I cancelled the subscription 11/11/2021 and pdffiller took my money via PayPal at 11/12/2021. I don't understand why. It's no honest. I don't even have an account on your site
Edit: I'm very satisfying with customer service of pdffiller. They returned my money. Thank you

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.
Does a minimal sufficient statistic always exist?
If there exists a minimal sufficient statistic, and this is usually the case, then every complete sufficient statistic is necessarily minimal sufficient(note that this statement does not exclude the option of a pathological case in which a complete sufficient exists while there is no minimal sufficient statistic).
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 .
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.
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 a complete statistic sufficient?
(Base's Lemma) If T(X) is complete and sufficient (for ), and S(X) is ancillary, then S(X) and T(X) are independent for all . In other words, a complete sufficient statistic is independent of any ancillary statistic.
