Anything that -su-, possibly with the -detail-, option throws up can be strored this way.

r(N)
r(sum_w)
r(mean)
r(Var)
r(sd)
r(skewness)
r(kurtosis)
r(sum)
r(min)
r(max)
r(p1)
r(p5)
r(p10)
r(p25)
r(p50)
r(p75)
r(p90)
r(p95)
r(p99)


Apart from that, also note commands like -collapse-...

BTW, what is the second mode?

Yes I see that. Quite clever. BUT what if it is something which is NOT
generated by a summary statistic . Like say the 2nd mode  ( assuming a
variable has 2 modes). Can I directly store it into a local variable ?

Thank you,
Ashim.

Hello everyone,

I have a question. Suppose I have a variable say - > age. Now I can do
egen j=max(age). Then I will have the max value of age in ONE
VARIABLE! Horrible waste of memory. I try to do local lj=max(age) and
that does not work. How can I conserve memory ? Is there something
basic which I have missed ?

Thank you,
Ashim.

PS : I do understand that I can do egen j = max (age ) and then say
local lj=j[1] and then -do drop j - but is there a better way ?
