Exclude vs Drop?

Hi what is the difference between exclude and drop? I tried the drop and override command, and compared it with the exclude and override command, and the simulation yielded different results. I thought it would be the same... should it be the same or have I done something wrong? I thought that the e...

Re: Clean up workpage

Okay, thanks for taking a look. Maybe you have time to add this functionality to EViews 11 ?

That is, the commands

    model.@vectorlist
    model.@scalarlist

would be highly appreciated.

Clean up workpage

Hi I have a workpage that contains a lot of unnecessary objects (i.e. series, scalars, vectors etc). In that workpage I have a model. I would like to remove all objects that are not related to the model. I can find the series objects that are not related to the model using the @wflookup("*"...

Facebook's Prophet in EViews

Hi Facebook has made a software package called Prophet that can be used for forecasting and that is becoming increasingly popular. It is open source and runs in R, see https://research.fb.com/prophet-forecasting-at-scale/ and https://facebook.github.io/prophet/ It would be great if you could create ...

Re: Small trick for add-in documentation/help text to appear in _this.display

Great idea, really useful. Here is an alternative way of opening an add-in documentation file. may be useful if the file is in pdf or another file format. it is assumed that the file is located in the same folder as the add-in: ' ... other parts of the addin programme %about="addin_about.pdf&qu...

Model: degree of controllability

In EViews there is a function called CONTROL that allows the user to solve for a control variable so that the target series matches a trajectory. This function only allows for one control variable, but the addin MCONTROL (http://forums.eviews.com/viewtopic.php?f=23&t=3286&p=54005&hilit=m...

Re: genr x from quarterly page to yield a particular annual growth rate

Hi Matt Thanks again for looking into this. I have tried to make an EViews model to solve for the quarterly growth rate given a specified annual growth rate. Attached are two programs. The first "create_example.prg" generates a series x and calls on another program "setpcy.prg". ...

Re: genr x from quarterly page to yield a particular annual growth rate

hi matt! thanks for your response. Yes, in that particular example, it follows what the quarterly growth rate must be. However, if more of the x-series is known during the time period under consideration, it becomes more complex. Consider again situation 3) described above, and illustrated in the pi...

Re: genr x from quarterly page to yield a particular annual growth rate

Thanks for this startz! and thanks for looking into this. But it does not give me the quarterly growth rate... it gives the annual growth rate (every q4). i would like to first specify the annual growth rate, and then generate a series, in a given smpl, that will yield this specified annual growth r...

Re: genr x from quarterly page to yield a particular annual growth rate

Hi In that particular example, by assuming constant quarterly growth (say g) in x, we have x = g * x(-1) which means that in our particular case: x1=x1 x2=g*x1 x3=g^2*x1 x4=g^3*x1 x5=g^4*x1 x6=g^5*x1 x7=g^6*x1 x8=g^7*x1 By inserting in the expression for the annual growth rate we get: !annualgrowthr...

Re: genr x from quarterly page to yield a particular annual growth rate

Hi startz Thanks for your suggestion! I see that I was somewhat imprecise in my first post. I would like the annual growth rate to be !annualgrowthrate=100 * ( (x8+x7+x6+x5) / (x4+x3+x2+x1)-1), where x1, x2, ..., x8 are observations of x in different quarters, where quarters 1,2,3,4 are in Year 1 an...

genr x from quarterly page to yield a particular annual growth rate

Hi Can you please describe how to generate a series in a quarterly page to match a specified annual growth rate? I am looking for a command of the type !annualgrowthrate=2.5 smpl 2018:2 2019 genr x = ... (?).... where the series x already exists in the workfile up to 2018:2 and the expression .... (...
