Note> i need the values in the place of *.

Solution

  • There are insufficient degrees of freedom for the calculations (including the standard deviation and the model term p-values). If this is from a DOE, you might need to augment your design with some additional runs. See Minitab support note http://support.minitab.com/en-us/minitab/17/topic-library/modeling-statistics/doe/basics/f--and-p-values-that-are-shown-as-asterisks/

    Typical successful Minitab regression output will show the P-values and standard deviation (as well as other statistics) in the ANOVA table and model summary as shown below:
