I love the site, I don't like all of the pop ups though! I constantly have to click out of the pop ups when opening a new form. That is my only complaint! But, all in all, I love this site and it helps me be more efficient.

A perfect user-friendly PDF Editor
`*I usually don't look forward to doing PDF editing as it is usually a nightmare. Nothing lines up, missing a feature you need, doesn't save correctly, or you can't send it, etc.
This is the first PDF editor that I actually have fun with, super user-friendly, fast learning curve, yet looks professional, is feature rich [in fact it has features the others don't have], and no problems saving and sending or later editing it again down the road. I am just ending a one month free trial offer and will gladly renew it as my permanent PDF editor.

I needed to cancel my account but had trouble doing so. The online customer support person Kara was so helpful! I am unemployed now like so many others and cannot afford the service any longer. But, once I get going again, this is the service I will sign up with. Wonderful service!

What is design resolution?
Definition of “Resolution” The length of the shortest word in the defining relation is called the resolution of the design. Resolution describes the degree to which estimated main effects are aliased (or confounded) with estimated 2-level interactions, 3-level interactions, etc.
What is aliasing in Doe?
DOE Glossary. Alias. Two or more effects are said to be aliased in an experiment if these effects cannot be distinguished from each other. This happens when the columns of the design matrix corresponding to these effects are identical.
What is aliasing in statistics?
Aliasing, also known as confounding, occurs in fractional factorial designs because the design does not include all the combinations of factor levels. The alias structure describes the confounding pattern that occurs in a design. Terms that are confounded are also said to be aliased.
What is resolution in Doe?
Resolution: A term which describes the degree to which estimated main effects are aliased (or confounded) with estimated 2-level interactions, 3-level interactions, etc. In general, the resolution of a design is one more than the smallest order interaction that some main effect is confounded (aliased) with.
What is confounding in factorial design?
Confounding. If the number of factors or levels increase in a factorial experiment, then the number of treatment combinations increases rapidly. When the number of treatment combinations is large, then it may be difficult to get the blocks of sufficiently large size to accommodate all the treatment combinations.
What is the main reason for using a fractional factorial design?
Use of fractional factorial designs. The basic purpose of a fractional factorial design is to economically investigate cause-and-effect relationships of significance in a given experimental setting. This does not differ in essence from the purpose of any experimental design.
What is the purpose of factorial design?
Factorial design involves having more than one independent variable, or factor, in a study. Factorial designs allow researchers to look at how multiple factors affect a dependent variable, both independently and together. Factorial design studies are named for the number of levels of the factors.
What is the main benefit of using factorial designs?
Factorial designs are more efficient than FAT experiments. They provide more information at similar or lower cost. They can find optimal conditions faster than FAT experiments. Factorial designs allow additional factors to be examined at no additional cost.
