comment Real-life examples of moving average processes
@Basj In the US, stores and manufacturers frequently issue coupons that can be redeemed for a financial discount or rebate when purchasing a product. They are often widely distributed through mail, magazines, newspapers, the internet, directly from the retailer, and mobile devices such as cell phones. Most coupons have an expiration date after which they will not be honored by the store, and this is what produces "vintages". Coupons possibly boost sales, but how many there are out there or how big the rebate is not always known to the data analyst. You can think of them a positive errors.

comment Multiple exogenous IV 2sls in Stata
@VictoriiaAlekhina I don't really understand your model and this is not my area of expertise. There's also not very much detail in your questions, so you are unlikely to get much useful advice from anyone else. I suggest asking a new question on the econ SE site, where you provde some additonal details (what is the outcome, what is the source of endogeneity, why are the isntruments relevant and exogenous, how did you implement the lag selection, etc.)

comment Statistics Software Survey?
Take a look at the links in my answer here. Also, it is Stata and not STATA.

comment Plotting confidence interval of multilevel logistic regression with y in OR
I have never heard of mcghermite. Do you mean melogit or meqrlogit? If so, take a look at the margins and marginsplot commands.

comment Propensity score matching in a longitudinal setting
For (3), if you use Leuven and Sianesi's psmatch2, you can use the bundled psgraph command. Similarly, Stata's own teeffects psmatch has a teffects overlap and teffects balance commands. On the modelling side, how long to do you expect of the effects from the treatment to last? Can people become treated at any point or are they all treated in the initial period? Does your actual data have more than 12 observations?

comment Ordinal Probit model in plain English
@emeryville We really don't. It's an assumption, which can be motivated by theory in some cases. Relaxing it is difficult.
