X |
H5D. Example: ‘X=hfile[[’X']]' where hfile is an hdf5r object containing a data matrix stored under label 'X'. |
X_control |
Matrix. features by control observations. Usually pulled from X but stored in memory so you don't have to pull the same control observations off of disk for every instrument. |
X_ids |
Sequence of strings with length equal to number of columns in X. Entries correspond to the instrument applied to that entry. |
X_vars |
Sequence of strings with length equal to the number of rows in X. Name of the feature measured in that row. |
targets |
List. Entries correspond to variables in X ('X_vars'), names correspond to the instrument targeting that variable ('X_ids'). These targets will be used to calculate causal effect sizes. |
max_med_ratio |
Float or NULL. Passed through to 'make_weights', NULL for no weights. |
filter |
Bool. True to filter the produced TCE matrix with 'fitler_tce'. |
rho |
Float. Initial learning rate for ADMM. |
lambda |
Float, sequence of floats of NULL. L1 regularization strength on inverse of X. If NULL, a logarithmicly spaced set of values between the maximum absolute off diagonal element of X and lambda_min_ratio times this value will be used. |
lambda_min_ratio |
Float, ratio of maximum lambda to minimum lambda. |
nlambda |
Integer. Number of lambda values to try. |
alpha |
Float between 0 and 1 or NULL. If > 0, the model will be fit once with gamma = 0 to find L0, then all subsequent fits will use gamma = alpha * L0 / D. Set to NULL to provide gamma directly. |
gamma |
Float or sequence of nlambda floats or NULL. Determinant regularization strength to use (for each lambda value). It is recommended to set alpha rather than setting this directly. |
its |
Integer. Maximum number of iterations. |
delta_target |
Float. Target change in solution. |
verbose |
0, 1 or 2. 2 to print convergence progress for each lambda, 1 to print convergence result for each lambda, 0 for no output. |
cv_folds |
Integer. Number of cross-validation folds to perform. |
mu |
rho modification parameter for ADMM. Rho will be increased/decreased when the dual constrant and primal constraint are off by a factor of > mu. |
tau |
rho modification parameter for ADMM. When called for, rho will be increased/decreased by the factor tau. |
solve_its |
Integer, number of iterations of bicgstab/lasso to run for each U and V update. |
ncores |
Integer, number of cores to use. |
warm_start |
Logical. Whether to use previous lambda value result as starting point for next fit. |
constraint |
One of "UV" or "VU". Constraint to use. |
DAG |
Bool. True to resitrict solutions to approximate DAGs. |
vars_to_use |
Sequence of strings. Entries in X_vars to keep. Default NULL to keep all. |
obs_to_use |
Sequence of bools. Indicator of columns of X to use in calculations. Useful for cross validation. |
train_prop |
Float between 0 and 1. Proportion of data to use for training in cross-validation. NOT USED. |
