It was a huge help on a critically important document. It was a downloaded pdf that I had to annotate, but Acrobat Pro was unable to edit it because Livecycle Designer was required. PDFfiller allowed me to do it entirely online and then print out. the required hard copy It was a godsend!

I do like the ease of use as this is the first time I have used a PDF application. I have just started using Adobe and unfortunately I think I like that better. Not positive yet.

I needed to make editable changes to a document in a short window of time. PDF Filler did the job! User-friendly and it saved the first draft so I had time to purchase a trial run of the software in order to save the final version on my PC. I wish that I could've been able to log in and get right to my previously saved work faster. The intro screen and the print screen were rather busy.

Awesome service! helpful for customers Ease of use! Love it. I love that i can change forms and addresses. This has been a lifesaver for work purposes. I wish you had more options as far as fonts go and wish you had more options as far as font sizes..something to think about

I had some troubles purchasing my subscription after my free trial and had a long wait using the chat feature. However, I called into the customer support line and had immediate amazing customer service in resolving my issue. My customer service rep was very detail in listening to my concerns and offering resolution. Because of the excellent customer service experience my PDfFiller representative delivered I proceeded with a one-year commitment of service and recommended these services to my family member.

To store the regression equation into Y1, hit VARS, choose Y-VARS, 1:Function, then 1:Y1. Hit ENTER. 'Line(ax+b) Y1' Should now appear. Hit ENTER to run the regression AND store it into Y1 simultaneously.
Enter your data in L1 and L2. Note: Be sure that your Stat Plot is on and indicates the Lists you are using. Go to [STAT] “CALL” “8: Line(a+bx). This is the LSL. Enter L1, L2, Y1 at the end of the LSL. [2nd] L1, [2nd] L2, [VARS] “Y-VARS” “Y1” [ENTER] To view, go to [Zoom] “9: ZoomS tat”.
Make sure your Plot 1 is ON. Select the Scatter Plots and the appropriate lists. Clear all functions in [Y=] Input data in L1 and L2. Go to [Stat] [Enter] to input data. Graph data points. Choose a regression from the list in [Stat] “CALL”. Go to [ZOOM] “9: Doomsday” to view the data with the regression curve.
Ensure List is set at L1, List is set at L2 and Store Regex is set at Y1 by pressing [VARS] [] 1:Function and 1:Y1. Scroll down to Calculate and press [ENTER]. The graphing calculator will display the form of the equation as (y=a+bx) and list the values for the two coefficients (a and b).
The Linear Regression Equation The equation has the form Y= a + bx, where Y is the dependent variable (that's the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the slope of the line and an is the y-intercept.
A linear regression line has an equation of the form Y = a + bx, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and an is the intercept (the value of y when x = 0).
A regression equation is used in stats to find out what relationship, if any, exists between sets of data. For example, if you measure a child's height every year you might find that they grow about 3 inches a year. That trend (growing three inches a year) can be modeled with a regression equation.
