Grouping and Percentage from raw data set

jonatan_velarde — Wed, 27 Jan 2016 20:36:29 GMT

My SAS friends:

I come to claim your help, to solve this problem:

Our Coleage PGstat, helped me a lot, and he haz constructed this command to solve the first part of the problem:

The data set is here:

data pn;
input ANIMAL    DAM    SIRE    DAM_BORN_DATE:mmddyy.    ANIMAL_BIRTH_DATE:mmddyy.     ANIMAL_BIRTH_TYPE    ANIMAL_BIRTH_WEIGHT         SEX$ ;
format animal_birth_date yymmdd10.;
format DAM_BORN_DATE yymmdd10.;
cards;
6561    4597    5982    06/13/2002    08/05/2008    1    4.8     M
6870    6561    5878    08/05/2008    10/13/2009    1    3.9     M
6971    6561    6626    08/05/2008    10/27/2010    3    2.3     M
6972    6561    6626    08/05/2008    10/27/2010    3    1.9     F
6973    6561    6626    08/05/2008    10/27/2010    3    2.2     F
7284    6561    6467    08/05/2008    12/21/2011    2    3.6     M
7285    6561    6467    08/05/2008    12/21/2011    2    3.3     F
7603    6561    7069    08/05/2008    05/07/2014    2    4     M
7603.1    6561    7069    08/05/2008    05/07/2014    2    3.2     M
;

proc sql;
/* Create table of number of offsprings for each parturition */
create table offsprings2 as
select
    dam,
    animal_birth_date,
    ANIMAL_BIRTH_WEIGHT,
    SEX,
    mean(distinct animal) as Animal
from pn
group by
dam,
ANIMAL_BIRTH_WEIGHT;
quit;

/* Create table of number of parturitions, mean number of offsprings per female
and parturition interval (in years) */
proc sql;
create table part_nb as
select
    dam,
    count(ANIMAL_BIRTH_WEIGHT) as Total_Lamb_Delivered,
    mean(ANIMAL_BIRTH_WEIGHT) as Mean_kg_Birth_by_Offpring format=4.1,
    case
        when count(animal_birth_date) > 1 then
            range(animal_birth_date) / (count(animal_birth_date)-1) / 365
        else .
        end as parturition_inte format=4.1
from offsprings2
group by dam;
quit;

proc print data = part_nb style(column) = [just=center];
where dam = 6561;
run;

And the Result is as follows:

Obs	DAM	Total_Lamb_Delivered	Mean_kg_Birth_by_Offpring	parturition_inte
2	6561	8	3.1	0.7

The next issue is about to describe the percentage and number of MALES and FEMALES produced by DAM, and the result would be as follows:

Obs	DAM	Total_Lamb_Delivered	Mean_kg_Birth_by_Offpring	parturition_inte	N_Males	Porc_Males	N_Females	Porc_Females
2	6561	8	3.1	0.7	5	62.5	3	37.5

Thank you for your help my Friends.

I'm going to suggest you should calculate your percentages outside and merge them in.

You should be able to run a proc freq to get the data initially, but then you may need to reformat it.

proc freq data=have noprint;
table dam*sex/out=summary_want outpct;
run;

Thanks for your suggestion Reeza.

I will test this command .

I will do it for PG.

proc sql;
/* Create table of number of offsprings for each parturition */
create table offsprings2 as
select
dam,
animal_birth_date,
ANIMAL_BIRTH_WEIGHT,
SEX,
mean(distinct animal) as Animal
from pn
group by
dam,
ANIMAL_BIRTH_WEIGHT;
quit;

/* Create table of number of parturitions, mean number of offsprings per female
and parturition interval (in years) */
proc sql;
create table part_nb as
select
dam,
count(ANIMAL_BIRTH_WEIGHT) as Total_Lamb_Delivered,
mean(ANIMAL_BIRTH_WEIGHT) as Mean_kg_Birth_by_Offpring format=4.1,
case
when count(animal_birth_date) > 1 then
range(animal_birth_date) / (count(animal_birth_date)-1) / 365
else .
end as parturition_inte format=4.1,sum(SEX='M') as N_Males,sum(SEX='M')/count(*) as Porc_Males ,sum(SEX='F') as N_Females,sum(SEX='F')/count(*) as Porc_Females
from offsprings2
group by dam;
quit;
proc print noobs;run;

Very nice
