multiple linear regression profilesphase II profile monitoringstatistical process control (SPC)In some statistical process control applications, the quality of a process or product is best represented by a functional relationship between a response variable and one or more explanatory variables. Different ...
In this part of the website, we extend the concepts fromLinear Regressionto models that use more than one independent variable. We explore how to find the coefficients for these multiple linear regression models using the method of least squares, how to determine whether independent variables are ...
Multiple linear regression formula Y = b0+ b1X1+ b2X2+ b3X3+...+ bpXp+ ε It is easier to use the matrix form for multiple linear regression calculations: Y = XB + Ε Ŷ = XB B = (X'X)-1X'Y [1 X11X12... X1p][Y1]ε1] ...
Calculation of the mean is one of the fundamental computations when performing linear regression analysis. The mean is unduly affected by outliers. Extremely outliers should be removed before beginning regression analysis. Not all outliers should be removed. An outlier should be removed if it is obvi...
These three new parameters were then verified against the FD and processed for regression analysis. As described in Sect. “Flow Chart”, data from all three wells were combined for PCA as individual wells yielded different PCA results. Due to this, it was no longer possible to use the ...

Dots are used to indicate values for two different numeric variables in a scatter plot, also known as a scatter chart or a scatter graph. The values for each data point are indicated by the position of each dot on the horizontal and vertical axes. Scatter plots are used to see how ...
