Hi,

I am very new to SAS programming (Enterprise Guide) and have tried combining procedures like Proc SQL, Proc Freq as well as macros, but no code worth posting here because they are full of errors. I would greatly appreciate any help!

**Input:**

I have been given a dataset consisting of 8000 observations (really there are 80million, but that's not important for the context). Sample below.

ID is a variable but is not needed in the output.

For each observation ONE of the obs_1, obs_2 or obs_3 can have the value of 1, OR they are all 0.

Obs | data_period | ID | EUR | riskgrade | obs_1 | obs_2 | obs_3 |

1 | 200801 | a | 20 | 3 | 0 | 1 | 0 |

2 | 200801 | b | 30 | 3 | 0 | 1 | 0 |

3 | 200801 | c | 50 | 4 | 0 | 0 | 0 |

4 | 200802 | a | 40 | 3 | 1 | 0 | 0 |

5 | 200803 | a | 20 | 4 | 0 | 0 | 0 |

6 | 200803 | c | 10 | 4 | 1 | 0 | 0 |

… | … | … | … | … | … | … | … |

80000 | 201512 | c | 7 | 4 | 0 | 0 | 1 |

**Desired output:**

Sample below (made in Excel).

I need one table for EACH riskgrade (in the real dataset there are 20 different, i.e. I want 20 tables).

Each data_period should be assigned to one row.

OBS with riskgrade 3 | |||||

data_period | SUM_obs_1 | SUM_obs_2 | SUM_obs_3 | # of observations | SUM of EUR during data_period |

200801 | 0 | 2 | 0 | 2 | 50 |

200802 | 1 | 0 | 0 | 1 | 40 |

… | … | … | … | … | … |

Total (in sample) | 2 | 2 | 1 | 3 | 90 |

OBS with riskgrade 4 | |||||

data_period | SUM_obs_1 | SUM_obs_2 | SUM_obs_3 | # of observations | SUM of EUR during data_period |

200801 | 0 | 0 | 0 | 1 | 50 |

200803 | 1 | 0 | 0 | 2 | 30 |

… | … | … | … | … | … |

201512 | 0 | 0 | 1 | 1 | 7 |

Total (in sample) | 1 | 0 | 1 | 4 | 87 |

PROC SUMMARY should do this.

Untested code

proc summary data=whatever; class riskgrade data_period; var eur obs_1 obs_2 obs_3; output out=want sum=sum_eur sum_obs_1 sum_obs_2 sum_obs_3 n(eur)=n; run;

@PaigeMiller Wow, many thanks for your quick response!

I tried out your simple yet effective code on my sample data and it works like a charm.

Will give it a go on my real data tomorrow.

Hi there,

I have a similar issue to aggregate my data file. I tried your code, but not apply to my data. I wonder if you can help me out as well.

This is my data:

COHORT_YEAR | FG_Status | Needy_Status | Time2Degree | LocalRace | Gender | count |

2008 | N | N | Not graduated | American Indian or Alaska Nat | F | 1 |

2009 | N | N | Within5Years | American Indian or Alaska Nat | M | 1 |

2008 | N | Y | 4YorLess | American Indian or Alaska Nat | F | 1 |

2010 | N | Y | 4YorLess | American Indian or Alaska Nat | M | 1 |

2008 | N | Y | 4YorLess | American Indian or Alaska Nat | F | 1 |

2012 | N | Y | 4YorLess | American Indian or Alaska Nat | M | 1 |

2008 | N | Y | 4YorLess | American Indian or Alaska Nat | F | 1 |

2008 | N | Y | 4YorLess | American Indian or Alaska Nat | M | 1 |

I have 15000 cases and I need to sum/aggregate the Headcount variable given all the 6 categorical variables, which means the output data keeps the categorical variables, and can be used in Excel pivot tables. As I am learning SAS not for long and tried many ways, but none of them works for me. Hope that you can help me out. Thanks in advance.
