validate_drift_dm: Validate a DDM object

In dRiftDM: Estimating (Time-Dependent) Drift Diffusion Models

Validate a DDM object

Description

Performs basic checks to ensure everything is as expected with the model. This function should be called whenever modifying a ddm object!

Usage

validate_drift_dm(drift_dm_obj)

Arguments

drift_dm_obj

the ddm object

Details

Checks:

• the flex_prms_object via validate_flex_prms()

• The prms_solve (that it is a named numeric vector check_if_named_numeric_vector() with the expected entries) and that nt, nx make sense. This may adjust t_max if t_max is smaller than max(RT) of the observed data

• The solver string (only a single string and that it refers to something that is actually implemented). If im_zero, then check if dirac delta on 0.

• checks that the list comp_funs only contains functions and that each function provides the expected arguments

• If PDFs exist, checks the names, lengths and data type

• Checks that log_like_val (if it exists) is a single numeric.

• Checks the data type name structure of obs_data

• Checks the b_coding (column, u_name_value and l_name_value).

Value

the unmodified ddm object, after it passed all checks
