2. When using a 2-level factorial design and the block size is not a power of 2, an optimal design can be used to construct an appropriate design.

The variance of the observations from the Hanning filter, if it is applied to a time series consisting of independent observations with constant variance σ2, is

Folding over a resolution III design is a technique to separate main effects from their two-factor interaction aliases. 

You are performing an experiment with a deterministic computer model. A reasonable choice of experimental design is 

Construct a 95% confidence interval for the regression coefficient for X1. The UCL is _______________.  

The advantage of the REML method is that it provides the standard errors of the variance components so that confidence intervals can be easily obtained. 

For a half fraction of a two-level factorial design the maximum resolution possible is equal to the number of factors. 

The random factors in an experiment are assumed to be normally and independently distributed. 

Center points can be used to determine: I. an estimate of pure errorII. an estimate of the sum of the quadratic effectsIII. if a process is running “as usual” 

The above stem and leaf diagram was constructed from a time series. What type of behavior does this time series exhibit?
