How to formulate quadratic function with interaction terms for the PLS fitting model?
I have two ideas about it. 1- i) Entering variables in quadratic form is done with the command I (variable ^ 2) - plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation = "LOO" You could also use a new variable NIR_sq <- (NIR) ^ 2 ii) To insert a square variable, use syntax I (x ^ 2) - it is very important to insert I before the parentheses. iii) If you want to make the interaction between...

Quadratic function with interaction terms for the PLS fitting model?
...tting a linear model, I want to fit my data with a quadratic function with interaction terms. But I am not sure how. I will use an example to illustrate my problem: Following the example in the PLS manual: ## Read data data(gasoline) gasTrain <- gasoline[1:50,] ## Perform PLS gas1 <- plsr(octane ~ NIR, ncomp = 10, data = gasTrain, validation = "LOO") where octane ~ NIR is the model that this example is fitting with. NIR is a collective of variables, i.e. NIR spectra consists of 401 diffuse reflectance measurements from 900 to 1700 nm. Instead of fitting with predict.octane[i]...

password encryption
Hi, I enabled password encryption and NT clients were able to connect. However, Windows 95 users were not able to connect any more unless they use smbpassword to reset the password (it's not an acceptable solution for our environment). If I used "update encrypted = yes", "encrypt passwords" then Windows 95 users can login with NIS password but not for NT users. How to

Fundamental formula and dataframe question.
...independent (X) variables such as chemometric datasets there is a convenient formula and dataframe construction that allows one to access the entire X matrix with a single term. Consider the gasoline dataset available in the pls package. For the model statement in the plsr function one can write: Octane ~ NIR NIR refers to a (wide) matrix which is a portion of a dataframe. The naming of the columns is of the form: 'NIR.xxxx nm' names(gasoline) returns... $names [1] "octane" "NIR" instead of... $names [1] "octane" "NIR.1000 nm" "NIR.1001...
