4. The simple regression model using the number of setup-hours as the independent variable achieves a comparable r2 to the multiple regression model. However, the multiple regression model includes an insignificant independent variable, number of setups. Adding this variable does not improve Williams’ ability to better estimate setup costs.

The Exponentially Weighted Moving Average (EWMA) is a statistic for monitoring the process that averages the data in a way that gives less and less weight to data as they are further removed in time. ... Linear regression models are often fit using the least squares approach, but may also be fit in other ways, such as by minimizing the "lack of ...

The simple weighted (w=1/Y²) linear model including all data was also unacceptable due to a very severe misfit as shown in Figure 3. Figure 3: X vs. Observed Y and Predicted Y for the simple weighted linear with a weighting factor W=1/Y2. The weighted polynomial regression gave also a …

1. Fit a linear regression trend line – plot the scatterplot and show the linear regression line going through the scatterplot. 2. You notice that there are some outliers that clearly influence the fit. To remedy this you decide to perform a ‘weighted least squares’. Described in page 280-285 of Helsel and Hirsch book (Chapter 10).

An autoregressive model is simply a linear regression of the current value of the series against one or more prior values of the series. The value of p is called the order of the AR model. AR models can be analyzed with one of various methods; including standard linear least squares techniques. They also have a straightforward interpretation.

The linear regression can be weighted by the calculated uncertainty on each bias. The regression coefficients including uncertainties (and their covariances) are calculated by the least squares method described in 5.b.ii.v0.2.

(iv) Plot the new regression line on the scatterplot (v) Use the residuals from this new regression line and repeat steps (ii) through (iv) about 2-3 times and the regression line will start to stabilize, giving you a ‘robust’ regression. Don’t go more than 3 times. (vi) Compare the GCV of this robust regression and that from (a) above.
