four suggestions

Postby ch2324 » Thu Mar 03, 2016 1:02 pm

Hi everybody
1) could you add a button "resample= @all " beside sample in the workfile to make easy to resample the data when i use "smpl date1 date2".
2) make "select all" when i clic in the right mouse, to select all proram (i can use CTRL+A).
3) make restore button or by right clic in mouse to restore defaut graph, (when i zoom in the graph i can not restore defaut graph :cry: !!!!!).
4) make function for differenced lag "@dlag(x,n1,n2, [s])" "x= series, n1=the start of d(x(n1)) , n2= the arrival of d(x(n2)), s=smpl", if i would have two diff laged variables i will put n1=1 and n2=2.
four mini suggestions.

I think the answer to 3 is hit the ESC key. I don't understand 4 either.

3-Great!
4-generate multi series differenced lag:
n1=represent the first number (order) that the series to be laged, and n2=the last
suppose i would to have 4 series diff lag, i will put @dlag(x,1,4) this function will generate four series diff lag d(@lag(x,1)),....,d(@lag(x,4)).
now suppose i would to start with the second order of lag i will put @dlag(x,2,4), this function will generate three series diff lag d(@lag(x,2)),....,d(@lag(x,4))
it would be nice if you can make function for @lag(x,n1x2,[s]), because @lag(x,n) generate just one order to be laged.
5- another question: this code generate 4 lags and diff lags, it can not put all y{!i} and dy{!i} in the group it put just the last series (y4 and dy4) in the group. any idea to solve this.

Code: Select all

for !i=1 to 4
series y{!i}=@lag(y,!i)
series dy{!i}=d(y{!i})
group lagy y{!i}*
group dlagy dy{!i}*
next

5:

Code: Select all

group lagg
group dlagg
for !i=1 to 4
series y{!i}=@lag(y,!i)
series dy{!i}=d(y{!i})
lagg.add  y{!i}
dlagg.add dy{!i}

What would you expect them to be filled with?

A group is a collection of series. If you delete the series what would you expect the group to show?

Data is stored in series. When you get rid of the series, you get rid of the data.
