binary time series modeling

amenalso225 — Fri, 23 Jun 2017 10:08:03 GMT

Dear SAS Communities,

I need to model a binary outcome (event = 1, nonevent = 0) depends on time. (please see the attached picture)

I would greatly appreciate guidance on which proceedures are applicable. The PROCs I tried thus far appear to model continuous outcomes.

Thank you!

Dan

What procedures have you tried? PROC LOGISTIC sounds like a place to start. Se documentation here

Are you looking at "time to event" type data? Such as time until failure of a part or how long the rat lives after exposure to your favorite carcinogen. Then you might want to look at survival analyis procedures such as Phreg, Lifereg, Lifetest or Probit

I am woundring how to model such data

Date	Rainfall amount (millimetres)	rain
1/1/00	0.4	1
1/2/00	0	0
1/3/00	0	0
1/4/00	3.4	1
1/5/00	1.4	1
1/6/00	0	0
1/7/00	0	0
1/8/00	0	0
1/9/00	0	0
1/10/00	2.2	1
1/11/00	0	0
1/12/00	0	0
1/13/00	0	0
1/14/00	0	0
1/15/00	0	0
1/16/00	0.4	1
1/17/00	0.8	1
1/18/00	0	0
1/19/00	0	0
1/20/00	0	0

The rain column is the binary outcome (dependent variable).
