Principal Component Analysis (PCA) is a statistical technique used fordata reductionwithout losing its properties. Basically, it describes the composition of variances and covariances through several linear combinations of the primary variables, without missing an important part of the original information....
I was thinking of treating everything as nominal categorical variables (even if there a two variables that are numerical), because from my understanding using the "lowest-common denominator" (like using a Chi-Square on a continuous variable) is doable (while sacrificing some statistical power, bu...
文本提到可以将主成分分析(PCA)应用到DoRF(一个数据库)中的曲线上,以获得相机逆响应函数的一个近似表示,称为EMoR(Empirical Model of Response)。EMoR模型是通过对逆响应函数曲线应用PCA并将它们分解为平均曲线g0 和一组基于协方差矩阵特征向量的加权和来构建的。

The PCA score for any of the Xi is just it's coefficient in each of the Ys. In my earlier example, the score for X2 in the first principal component (Y1) is 1.76. The way PCA does this magic is by computing eigenvectors of the covariance matrix. To give a concrete example, ...
