There are several ways to get at this information, one being to -trace- the thing and scroll up to the point where it is created afterwards. -set tracehilite- is very helpful in this exercise...
```
******
sysuse census, clear
set tr on
kwallis2 medage, by(region)
set tr off
*******

```
Next possibility: If you -log- the process, you can look at the log in a text editor and search for "Adjusted"...
```
```
Or you look at kwallis2.ado, for instance with NJC`s -ssc d fedit- where you will find lines 123-124:
```
*******
local c1=(1-\$S_level/100)/(2*(`maxGrp'-1))
di in gr "(Adjusted p-value for significance is " %7.6f `c1' ")" _n
*******

```
If you want, create your own copy of kwallis2.ado and toss in a -pause- so you can inspect the state of the world when line 123 is processed...

```Dear Statalisters,

p-values for significance when the Kruskal-Wallis Test is statistically
significant?

Cheers!
