Dear sir, I would like to employ the AUTOMATIC function in GROCER toolbox to perform automatic regression starting with a rather LARGE set of variables and ending with the few that are most significant. However, I have noticed the following problems using the example attached:
1. Programme works with only 3 initial variables specified (see line 30 in attached file), which works, but line 31 with only 6 starting variables complains of TOO MANY EXOGENOUS VARIABLES 2. When it runs with 3 starting variables, the R2 value is not specified. How can I get this calculated and used. 3. The help files included with the AUTOMATIC package does not seem to answer these questions. ANY ASSISTANCE WILL BE GREATLY APPRECIATED -- Samuel Ogbonna Enibe BEng (Nig), MSc (Reading, England), PhD (Nig) Professor of Mechanical Engineering Director, National Centre for Equipment Maintenance & Development University of Nigeria, Nsukka, Nigeria Tel: +2348063646798 Email: [email protected] [email protected]
