Standardized Sample Mean of Moment Functions
m_hat(x_data, MARGIN = 2)
x_data
an n x k matrix of evaluated moment functions.
MARGIN
a vector giving the subscripts which the function will be applied over. E.g., for a matrix 1 indicates rows, 2 indicates columns.
a vector of the standardized sample mean of the moment functions.
