....of input parameters very easily. 3.1. 3 Partial Least Squares Regression The last regression modeling technique under discussion is partial least squares regression (PLSR) This method is widely used in chemometrics, a field of chemistry that uses statistical methods for chemical data analysis [18]. The general idea of the PLSR algorithm is similar to that of PCR. A reduced set of parameters that sufficiently describe the input data is found and then used as the regressors on Y. The notion of factor loadings and scores introduced in the context of PCR is also used in PLSR. Instead of one ....
....another for the response. The algorithm for one response follows. Let A max be the maximum number of PLSR factors. At the start of the algorithm, A max should be larger than anticipated to allow for unexpected factors. The following steps are then performed for each factor a = 1, 2, A max [19][18][20] 1. Determine the loading weight vector : The loadings are orthonormal vectors which maximize the covariance between and . In other words, relates the input and response, and is used to calculate the response in the model. 2. Estimate the scores : indicates how much of the response ....
