mixed_info_table#
View page sourceThe CppAD Mixed Information Table#
Discussion#
A new version of this table is created each time a fit_command is run. The table contains information about the size of certain cppad_mixed objects. It is useful for seeing how the problem setup affects the size (and hence time) of the problem. For example, how different the size is when one uses a hold_out_command to sub-sample the data.
Format#
Each row of this table has the following information:
mixed_info_id#
This column
has type integer
and is the primary key for this table.
Its initial value is zero, and it increments by one for each row.
mixed_name#
This column
has type text
and has a different value for every row;
i.e., the names are unique and can act as substitutes for the primary key.
Some of the possible values for mixed_name are listed below.
There may be other (unspecified) rows in this table.
mixed_value#
This column has type text
and is
the value for the corresponding name.
n_fixed#
If mixed_name is n_fixed
,
mixed_value is the number of fixed effects.
n_random#
If mixed_name is n_random
,
mixed_value is the number of fixed effects.
quasi_fixed#
If mixed_name is quasi_fixed
,
mixed_value is one (zero) if we are a using a quasi-Newton (Newton)
method for optimizing the fixed effects.
A_nr#
If mixed_name is A_nr
,
mixed_value is the number of rows in the
liner constraint matrix A
(the matrix has n_fixed columns).
A_nnz#
If mixed_name is A_nnz
,
mixed_value is the number of non-zeros in the
liner constraint matrix A.
ran_like_fun.size_var#
If mixed_name is ran_like_fun.size_var
,
mixed_value is the number of variables in the
algorithm that maps the fixed and random effects to the part of
the likelihood that depends on the random effects.
fix_like_fun.size_var#
If mixed_name is fix_like_fun.size_var
,
mixed_value is the number of variables in the
algorithm that maps the fixed effects to the part of
the likelihood that does not depend on the random effects.
