Consistency and retention

[Manuel]

Hi there,

I am starting to use TNT, so maybe this is a very easy or silly
question. I am trying to estimate the Consistency and retention index
with TNT, and I am not getting it. Could someone give some
information?

thanks a lot

Use the macro stats.run. I think that this macro is included within
all TNT releases. If not, the code is very easy:

**

macro= ;
report- ;
var =
0 themin
1 themax
+ CIs [ ( ntrees + 1 ) ]
+ RIs [ ( ntrees + 1 ) ]
+ this
;
set themin minsteps ;
set themax maxsteps ;
loop 0 ntrees
progress #1 (ntrees+1) Calculating indices... ;
set this length[#1] ;
set CIs[#1] 'themin'/'this' ;
set RIs[#1] ('themax'-'this')/('themax'-'themin') ;
stop
progress/ ;
report= ;
macfloat 3 ;
maketable CIs Consistency index ;
maketable RIs Retention index ;
proc/ ;

**

So, paste, copy and run ;)

cheers
