Dear all
Firstly I want to say that i am a new Minitab user and don't have any strong background in statistic. However, I want to use Minitab to determine the optimized reaction condition. The reaction relates with the two dominant factors (mixing times (4 levels) and agitator speeds (3 levels)). The reaction is monitored by measuring the change of SG (Response), which is targeted at 0.8067.
Does anyone could kindly help me step by step? I did try on ANOVA-GLM, but the result is shown as follows:
General Linear Model: SG versus Speed, Mixing Time
Factor Type Levels Values
Speed fixed 3 250 rpm, 400 rpm, 550 rpm
Mixing Time fixed 4 5 min, 10 min, 15 min, 20 min
Analysis of Variance for SG, using Adjusted SS for Tests
Source DF Seq SS Adj SS Adj MS F P
Speed 2 0.0000073 0.0000073 0.0000037 **
Mixing Time 3 0.0000006 0.0000006 0.0000002 **
Speed*Mixing Time 6 0.0000001 0.0000001 0.0000000 **
Error 0 * * *
Total 11 0.0000080
** Denominator of F-test is zero.
Also I couldn't optimized the condition by using response optimizer function? Please advice me the solutions.
Wish your day is a blessed one
Thank you so much..
