Regression (using excel) For given data of Y versus X for i. Some design calculations require these data to be accurately correlated by various algebraic expressions which provide Y in (unit y*) as a function of X in (unit x*). Find the following 1. Using graphical method; find the best function represents Y as a function of X What will be the Y value at X=value ? 2. Using numerical method; find the best polynomial function represent Y as a function of X What will be the X value at Y=value ? Regress the data using linear regression. Regress the data using nonlinear regression. Calculate the R value for Power function
