To carry out the lack or lack of fit test, it is necessary to partition the sum of squares due to random error in two: a. One due to the fitted model and one due to the pure error b. One due to lack of fit and one due to the fitted model c. One due to the total variation of the experiment and another due to the estimated model d. One due to lack of fit and one due to pure error Explain clearly each option please
= 4 levels and factor B has b 5 levels. A F In a 2-factor factorial experiment, factor A has a balanced design is used with 10 replications per treatment combination. Then the number of degrees of freedom for the interaction effect in the ANOVA procedure is and the number of degrees of freedom for the error is Both final answers are whole numbers.
