Simulate Heterogeneous data with a band structure, which can be used in GGMM(data,...)
for estimating the structure of the Gaussian graphical network.

n |
Number of observations for each group, default of 100. |
p |
Number of covariates for each observation, default of 200. |
M |
Number of latent groups for the simulated dataset choose 2 or 3, default of 3. |
mu |
The mean difference among groups. If M=3, the mean of three groups are -mu,0,mu, respectively. If M=2, the mean of two groups are 0,mu, respectively. |
type |
C_{i,j}=≤ft\{\begin{array}{ll} 0.5,&\textrm{if $≤ft| j-i \right|=1, i=2,...,(p-1),$}\\ 0.25,&\textrm{if $≤ft| j-i \right|=2, i=3,...,(p-2),$}\\ 1,&\textrm{if $i=j, i=1,...,p,$}\\ 0,&\textrm{otherwise.} \end{array}\right. |
