An implementation of fitting generalized linear models on second-order tensor type data. The functions within this package mainly focus on parameter estimation, including parameter coefficients and standard deviation.
git clone https://github.com/yuting1214/TensorTest2D
R CMD INSTALL TensorTest2D
or in R console window type the following
install.packages("TensorTest2D")

# Simulate data
n <- 500 # number of observations
n_P <- 3; n_G <- 64 # dimension of 3-D tensor variables.
n_d <- 1 # number of numerical variable, if n_d == 1, numerical variable equals to intercept.
beta_True <- rep(1, n_d)

X <- array(rnorm(n*n_P*n_G), dim=c(n_P, n_G, n))
## Regression Data
y_R<- as.vector(W%*%beta_True + X%hp%B_True + rnorm(n))
