[求助]
誰能教教我怎么對響應(yīng)面的結(jié)果進(jìn)行分析 已有7人參與
|
|
我的響應(yīng)面做完了,但是其中的失擬項后面沒有P值和F值,因此我就不能確定其的顯著性,我想知道這是為什么,我已經(jīng)做了2次了,望大家賜教。急啊~~~~~~ 謝謝了 |

There is only a 0.03% chance that a "Model F-Value" this large could occur due to noise. Values of "Prob > F" less than 0.0500 indicate model terms are significant. In this case B, C, AB, A++2+-, B++2+-, C++2+- are significant model terms. Values greater than 0.1000 indicate the model terms are not significant. If there are many insignificant model terms (not counting those required to support hierarchy), model reduction may improve your model. Std. Dev. 0.050 R-Squared 0.9649 Mean 5.50 Adj R-Squared 0.9199 C.V. % 0.91 Pred R-Squared 0.4391 PRESS 0.28 Adeq Precision 14.663 The "Pred R-Squared" of 0.4391 is not as close to the "Adj R-Squared" of 0.9199 as one might normally expect. This may indicate a large block effect or a possible problem with your model and/or data. Things to consider are model reduction, response tranformation, outliers, etc. "Adeq Precision" measures the signal to noise ratio. A ratio greater than 4 is desirable. Your ratio of 14.663 indicates an adequate signal. This model can be used to navigate the design space.

In the Diagnostics Node, Select Case Statistics from the View Menu. Proceed to Diagnostic Plots (the next icon in progression). Be sure to look at the: 1) Normal probability plot of the studentized residuals to check for normality of residuals. 2) Studentized residuals versus predicted values to check for constant error. 3) Externally Studentized Residuals to look for outliers, i.e., influential values. 4) Box-Cox plot for power transformations. If all the model statistics and diagnostic plots are OK, finish up with the Model Graphs icon. |
