下面的SPSS16里关于做偏最小二乘的帮助,请看一下应该如何做呀,好象要下载一个模块,还不是SPSS的
Availability. PLS is an extension command that requires the Python Extension Module to be installed on the system where you plan to run PLS. The PLS Extension Module must be installed separately, and the installer can be downloaded from http://www.spss.com/devcentral.
Note: The PLS Extension Module is dependent upon Python software. SPSS is not the owner or licensor of the Python software. Any user of Python must agree to the terms of the Python license agreement located on the Python Web site. SPSS is not making any statement about the quality of the Python program. SPSS fully disclaims all liability associated with your use of the Python program.
Tables. Proportion of variance explained (by latent factor), latent factor weights, latent factor loadings, independent variable importance in projection (VIP), and regression parameter estimates (by dependent variable) are all produced by default.
Charts. Variable importance in projection (VIP), factor scores, factor weights for the first three latent factors, and distance to the model are all produced from the Options tab.
谁知道具体该如何做呀
