Transform multiple response dataset from polytomous mode into indicator mode

[Donald Villanueva]

Hello. I would like to ask if there is a Stata command to transform multiple response dataset from polytomous mode into indicator mode. Thank you in advance.

welcome to this forum.
Do you mean -pca-?

Hi Carlo,

It is not PCA. I am referring to the structure of the multiple response dataset. I am aware that there are two types of data structures for multiple responses variable: polytomous mode and indicator or dichotomous mode (as demonstrated below). Is there a Stata command to directly transform multiple response data from polytmous mode into indicator or dichotomous mode and vice versa? Thanks in advance.

Polytomous mode

id	q1_1	q1_2	q1_3	q1_4	q1_5	q1_6
1	1	6	0	0	0	0
2	5	2	1	0	0	0
3	5	0	0	0	0	0
4	3	0	0	0	0	0
5	6	3	0	0	0	0

Indicator or dichotomous mode

id	value_1	value_2	value_3	value_4	value_5
1	1	0	0	0	1
2	1	1	0	1	0
3	0	0	0	1	0
4	0	0	1	0	0
5	0	0	1	0	1
