Ordering frequences in proc tabulate (order=freq)

12m ago

Dear experts,

I don't succeed in ordering frequences when using var and statistic "sum".

Am I mistaking something?

Here's the program:

proc tabulate data=sashelp.class f=6.;
CLASS height/order=freq;
var weight;
table height all,weight*sum/rts=25 condense;
run;

Here's the result:

                            Weight
                       |------------|
                                  Sum
|----------------------- ------------|
Height
|-----------------------|
62.5                             197
|----------------------- ------------|
66.5                             224
|----------------------- ------------|
69                               113
|----------------------- ------------|
56.5                              84
|----------------------- ------------|
65.3                              98
|----------------------- ------------|
62.8                             103
|----------------------- ------------|
63.5                             103
|----------------------- ------------|
57.3                              83
|----------------------- ------------|
59.8                              85
|----------------------- ------------|
59                               100
|----------------------- ------------|
51.3                              51
|----------------------- ------------|
64.3                              90
|----------------------- ------------|
56.3                              77
|----------------------- ------------|
72                               150
|----------------------- ------------|
64.8                             128
|----------------------- ------------|
67                               133
|----------------------- ------------|
57.5                              85
|----------------------- ------------|
All                             1901

As you can see, frequences are not ordered.

I cannot use proc freq, because I'd like to add some variables in the heading.

Thank you all,

Daniela

Try option order=internal; proc tabulate data=sashelp.class f=6. ; CLASS height/order=internal; var weight; table height all,weight*sum/rts=25 condense ; run;

Hello,

The documentation states:

FREQ - orders values by descending frequency count.

Thus , in your example the count is 1 for all the observations listed except for height=62.5 which is twice met therefore is listed first. You may have expected the results to be orderred by the sum but the results are ordered by the frequency count.

Thank you very much for the clarification. Now is clearly for me why the output has such an order.

I've already solved my problem by applying a 'multilabel notsorted' format to the variable in the order I want, but I'd still like to find a easier way to order the variable (directly from the tabulate).

Is there any method to solve my necessity?

Thank you in advance.

I tried it, but It doesn't work.

I don't believe you have quite adequately described what your desired order may be. Are you trying to order by the value of the statistic SUM? That is not an option in Tabulate. You would have to summarize the data first and then have a variable that could apply order to.

Yes, I'd have liked to order by the value of the statistic SUM... now I know it isn't the way.
Thank you for the suggestion. I'll try it.
