wasn't aware i was paying for it until i saw the charge on my bank statement. that should have been clearer. will know more about how much i like it when i print the documents i have entered. i also would like a tech support number as i am very bad with computers.

App produces error during install for smartphones. Should favor browser entry, or at least make link more prominent.
Also, the way that some of the advanced features are not available to a subscription is a bit misleading they way they are presented IMO... At the very least, the base subscription should provide limited quantities of some of the more advanced features... (monthly counter etc.) ~ Because the casual user may really benefit from these features (in low volume.) And there's little incentive to not just "get by" with the free services if they're not available.

Need to fill out forms electronically
Need to fill out forms electronically, avoiding hand written forms that ulitmately creates errors and makes your efforts for not. Love this company helped in a pinch and was such a useful easy tool to use, I recommend it.

Great software, some things are not intuitive
You can edit documents, replace text, add fillable fields, etc. Great for documents that are used often and just need a few details changed.
"Replace text" can be difficult to use. Also the process of saving a document is kind of clunky.

Great online chat support!
Support when I've needed it has been great which I can rarely say about most companies these days. While the program tends to be a little cumbersome it works for what I need it to. When I have issues the online chat support has been great an very little wait to get to someone. John resolved my issue over the weekend and Kara fixed the one I had this morning - I really appreciate both their help!

Smooth fillable process
Smooth fillable process. It's just the end of the process, saving the document and accessing it that I still need to get used to. I don't feel too comfortable as I feel like my documents are not easily accessible if I forget my password. I guess it's a matter of getting used to. Also is there a charge sometime in the future for this?

How do you perform system identification?
Measure the input and output signals from your system in time or frequency domain. Select a model structure. Apply an estimation method to estimate value for the adjustable parameters in the candidate model structure.
What is model identification?
The field of system identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments for efficiently generating informative data for fitting such models as well as model reduction.
What is a just identified model?
According to this PDF, when number of instrument variable equals to the number of endogenous components, the model is said to be just-identified. If number of instrument variable is bigger than the number of endogenous components, the model is said to be over-identified.
What do you mean by system identification?
System identification is a methodology for building mathematical models of dynamic systems using measurements of the system's input and output signals. The process of system identification requires that you: Measure the input and output signals from your system in time or frequency domain. Select a model structure.
What is identification econometrics?
Identification, in econometrics, is a problem which tells whether structural parameters can be obtained or not from reduced form parameters.
What is identifiability in statistics?
In statistics, identifiability is a property which a model must satisfy in order for precise inference to be possible. A model is identifiable if it is theoretically possible to learn the true values of this model's underlying parameters after obtaining an infinite number of observations from it.
What is ARX model?
ARX time series models are a linear representation of a dynamic system in discrete time. Putting a model into ARX form is the basis for many methods in process dynamics and control analysis. Below is the time series model with a single input and single output with k as an index that refers to the time step.
What is state space model?
State-space models are models that use state variables to describe a system by a set of first-order differential or difference equations, rather than by one or more nth-order differential or difference equations.
