1----- <~dex2k\preqdisc.top> Discussion: Prediction Equation 2 3Discussion: Prediction Equation 4 5The prediction equation for 2**k designs are of 6the form 7 8 Y = MU + 0.5*(imprtant factors) 9 10For example, for the 2**3 full factorial design, 11the recommended prediction equation is 12 13 Y = MU + 14 0.5*( B1*X1 + B2*X2 + B3*X3 + 15 B12*X1*X2 + B13*X1*X3 + 16 B23*X2*X3 + 17 B123*X1*X2*X3 ) 18 19where all of the parameters will be replaced 20by the least squares estimate. 21In practice, we would include only those terms which 22turn out to be "large" (significantly non-zero), as 23determined by any of the subsequent menu items 24in this section. 25 26
