Sample results are obtained by plugging sample absorbance values into the linear regression formula. This is usually performed automatically by direct read-out meters. Second-source Standard: A standard prepared from a source independent (e.g., different vendor, different lot #, etc.) from that used to prepare the calibration standards.

where sx and sy are the standard deviations for x and y. Notice we are looking at how far each point deviates from the average X and Y value. (the true correlation is zero) versus (the true correlation is not zero). The formal test for the correlation has the test statistics with n-2 degrees of freedom.

Residual Analysis for Multiple Regression (Sec. 12-2) Very similar to case for Simple Regression. Only difference is to plot residuals versus each independent variable. Similar interpretations of plots. A review of plots and interpretations: Residuals: Plots (see prototype plots in book and in class):

2) Feeding formula( (7): For most patients a standard polymeric formula is usually appropriate. 3) Position( (7): Unless contraindicated, the head of bed should be elevated at 45( at all times. If this is not feasible, the head of the bed should be elevated as much as possible. 4) Feed initiation( (7):

If the errors are heteroskedastic and you use the homoskedasticity-only formula for standard errors, the standard errors are wrong. The two formulas coincide (when n is large) in the special case of homoskedasticity ...
