This function is to make dummy variables using a discrete variable.
Usage
makeDummy(tZ)
Arguments
tZ
An input vector
Value
Returns dZ, a matrix of size length(tZ)-by-card(tZ) :
The ij-th element in dZ is 1 if tZ[i] is equal to the j-th largest value of tZ.
And the ij-th element in DZ is 0 otherwise.
The row sum of dZ must be 1 by construction.
