Dataframe with data for the likelihood computations.
timestamp_col
Column which determines time stamps. For now only
natural numbers can be used.
entity_col
Column which determines entities (e.g. countries, people)
dep_var_col
Column with dependent variable
lin_related_regressors
Vector of strings of column names. Which subset of regressors is in non trivial
linear relation with the dependent variable (dep_var_col). In other
words regressors with non-zero beta parameters.
which_matrices
character vector with names of matrices which should be
computed. Possible matrices are
"Y1", "Y2", "Z", "cur_Y2", "cur_Z",
"res_maker_matrix". Default is
c("Y1", "Y2", "Z", "cur_Y2","cur_Z", "res_maker_matrix") in which case
all possible matrices are generated
