Dear _all,
I am puzzled by the fact that -histogram- does not seem to properly
select cases based on a comparison with a saved result after -summarize-:
/**********************/
clear
cap graph drop _all
set obs 1000
g x=exp(rnormal())
su x, de
local p95=r(p95)
di r(p95)
hist x if x<r(p95), name(ha)
hist x if x<`p95', name(hb)
hist x, name(hc)
/**********************/
the first histogram (with the -if- statement and the reference to
r(p95)) is identical to the last histogram (without the -if- statement).
When r(p95) is saved to a local macro which is then used in an -if-
statement, it works fine (second graph).
Now, I have not tried all types of graphs, but -kdensity- seems to
behave as expected:
/**********************/
clear
cap graph drop _all
set obs 1000
g x=exp(rnormal())
su x, de
local p95=r(p95)
di r(p95)
hist x if x<r(p95), name(ka)
hist x if x<`p95', name(kb)
hist x, name(kc)
/************************/
Best,
Antoine
