What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It is somewhat confusing at first, but after learning the program it is very helpful and convenient to use! I enjoy all of the different options regarding the tools to fill out a PDF, for me it was a rental application for an apartment that i needed to fill out. The one thing I did not like is that after i had filled out my entire application via the pdffiller app, i could not e-mail the pdf until i paid for a plan. Somewhat disappointing, but regarding the program it is a good one.

My QuickBooks won't let me print W2's unless I sign up for their payroll service. We have 2 employees! Not worth the expense! With PDFfiller, I was able to print W2's for much more reasonable price!

Having the capability to complete my documents on line and print makes my job run more effective and efficient. When I utilize many of the same forms multiple times it is very time saving to be able to go in make the necessary changes and print. This programs saves valuable work time, and keeps me organized.

Very simple and incredibly useful. This is my secret weapon as I can change, modify or update any PDF document and have it ready to go within minutes. Probably my most useful app.

What do you like best?
I love that the physician can dictate the form to me and I can easily load the form and type it up for him. He is extremely busy and needs to fill these forms out on his own time. Now I can do it for him saving him the time to focus on face to face visits with his patients.
What do you dislike?
It is very new to me, so I am uncertain if there is anything at this point I don't like, as I am unfamiliar with a good portion of the program. But what I have used thus far is great!

Stupid-Easy to use Very easy to get used to. This should be called PDF-Text for Dummies. I literally had this program up and running in less than 5 minutes of downloading and installing it. Wish it was a little cheaper. If you are not using it often it hard to justify the monthly cost. It may be better to go with the annual subscription instead of the monthly in some cases.

it took me a little to figure out some… it took me a little to figure out some things as I am not as tech savy as the younger generations but was able to navigate and get the forms filled out.

I have used PDF filler to change dates on my job seeking paperwork. I use PDF filler to fill in work forms. I love that I can get my signature easily, and ask others to sign forms! This is great for school paperwork.

Take the whole dataset consisting of d+1 dimensions and ignore the labels such that our new dataset becomes d dimensional. Compute the mean for every dimension of the whole dataset. Compute the covariance matrix of the whole dataset. Compute eigenvectors and the corresponding eigenvalues.

The main idea of principal component analysis (PCA) is to reduce the dimensionality of a data set consisting of many variables correlated with each other, either heavily or lightly, while retaining the variation present in the dataset, up to the maximum extent.
PCA should be used mainly for variables which are strongly correlated. If the relationship is weak between variables, PCA does not work well to reduce data. Refer to the correlation matrix to determine. In general, if most of the correlation coefficients are smaller than 0.3, PCA will not help.
Principal Components Analysis (PCA) is a technique that finds underlying variables (known as principal components) that best differentiate your data points. Principal components are dimensions along which your data points are most spread out: A principal component can be expressed by one or more existing variables.
PCA is a method used to reduce number of variables in your data by extracting important one from a large pool. It reduces the dimension of your data with the aim of retaining as much information as possible.
PCA is mostly used as a tool in exploratory data analysis and for making predictive models. PCA is the simplest of the true eigenvector-based multivariate analyses. Often, its operation can be thought of as revealing the internal structure of the data in a way that best explains the variance in the data.
