Hi! I am pretty new to coding in SAS, so please let me know if you need more info to answer my question. I'm using SAS Studio University Edition.

I have a data set (BBMP) with 3 independent variables (PRED, MANIP, and SP), a TRT column that identifies observations by PRED_MANIP_SP combination, and a binomial response (PACT) at each of 12 observation times (TIME) (See attached spreadsheet)

What I want to do is collapse over TIME so that I can create a variable for the number of of positive responses (1) for each TRT (new variable = Y) and a total N for each TRT that tallies TIME (new variable = N; subset here has N=12 for each REP and N=24 for each TRT), such that I can eventually create a proportion Y/N. How would I program a data step in SAS to create Y and N for me rather than manually creating a new spreadsheet with these variables?

Sample data:

REP | PRED | MANIP | SP | TRT | TIME | PACT |

HuMPAnN1 | An | N | Hu | HuMPAnN | 1 | 0 |

HuMPAnN1 | An | N | Hu | HuMPAnN | 2 | 1 |

HuMPAnN1 | An | N | Hu | HuMPAnN | 3 | 0 |

HuMPAnN1 | An | N | Hu | HuMPAnN | 4 | 0 |

Generally, users won't download an XLSX file, you'll get a faster response if you post a small sample of data in your post.
