OK, now I see what you mean.  But given that -est save filename- can
have a pretty weird string for -filename- it might not be so easy for
-est- or you to use the proposed feature, and it only saves you one
line of code:

webuse bangladesh, clear
qui logistic c_use urban age child*
tempfile bangla1 bangla2
estimates save `bangla1', replace
qui logistic c_use urban age
estimates save `bangla2', replace
clear all
est use `bangla1'
di "Now store est as `bangla1' --really?"
est sto bangla1
est use `bangla2'
lrtest bangla1 .

You have to do this for each saved estimation result before you can start running e.g. likelihood-ratio tests. My idea was to combine these two necessary steps into one, with the help of a new option "store", like "estimates use filename, store".

> No, it wouldn't be great.  I think you mean such a "feature" to bring the whole dataset back into memory.  If you saved the data along with every estimate (the only way to implement such a "feature"), you might fill up all the available hard disk space in your country in a matter of days.  Seriously, if you're using a large dataset (a few GB) and you saved it separately along with every estimate, you would run out of space very quickly.
