Scatter plot with linear fit of two-period independent variable and one dependent variable.

[Zuhumnan Dapel]

Dear All,
I've data on y for period 1 and data on x for periods 4 and 5.

I want to graphically depict this using the

aaplot

command. Possible and any lead?

Thanks,
Dapel

aaplot is from SSC as you are asked to explain (FAQ Advice #12).

Otherwise -- particularly without a data example (see same place in FAQ Advice) -- I have no clear idea what you want. Perhaps it's

scatter x period if period == 1 | scatter y period if inlist(period, 4, 5)

I am guessing wildly. Is this panel data?

[Zuhumnan Dapel]

Thanks! Not really a panel. I've got Xi1, Xi2 and Yi1. It's pretty straight forward to depict the relationship between Xi1 and Yi1. But what if I want to add a best fit of Xi2 to the graph?

[Nick Cox]

Still no data example. I hesitate to ask this after you've posted 346 times here but are you aware of the request to read and act on http://www.statalist.org/forums/help ?

I am still guessing and your language and your notation seem at odds too, but

scatter Yi1 Xi1 || scatter Yi1 Xi2 || lfit Yi1 Xi1 || lfit Yi1 Xi2

may give you some ideas. No more from me.

You've done me a world of good. Thanks a million! The last code you posted gave me exactly what I'm looking for.

Thanks again,
Dapel

P.S.

I used

clear

. set obs 20
obs was 0, now 20

. generate randnum = uniform()

. generate y = uniform()

. generate yi1 = uniform()

. generate xi1 = uniform()

. generate xi2 = uniform()

. scatter yi1 xi1 || scatter yi1 xi2 || lfit yi1 xi1 || lfit yi1 xi2
