| ===Purpose===
| | Working with False-color images, figure 6. |
| | |
| Calculates matrix for T^2+Q contributions for PCA and MPCA.
| |
| | |
| ===Synopsis===
| |
| | |
| :[tsqqmat,tsqqs] = tsqqmtx(x,model,wt)
| |
| | |
| ===Description===
| |
| | |
| ====Inputs====
| |
| * '''x''' = data matrix [class double or dataset]
| |
| * '''model''' = PCA or MPCA model standard model struture (see PCA).
| |
|
| |
| ====Optional Inputs====
| |
| * '''wt''' = {sqrt((M-K-1)/(M-1))}, 0<=wt<=1 scalar weighting for contributions 0<wt<1 gives combined T^2 and Q statistics where M is the number of calibration samples and K is the number of PCs.
| |
| ::wt = 1 gives T^2 and T^2 contributions
| |
| ::wt = 0 gives standarized Q residuals
| |
|
| |
| ====Outputs====
| |
| * '''tsqqs''' = combined Hotelling's T^2 + Q residual
| |
| * '''tsqqmat''' = matrix of individual variable contributions such that
| |
| ::<tt>tsqqs(i) = tsqqmat(i,:)*tsqqmat(i,:)';</tt>
