Implement test for options

[MaxBlesch]

Suggested Additional Checks for check_options_and_set_defaults

• Check for continuous_states dict in options dict
• Check for missing continuous_states keys always present like wealth:
• Ensure wealth exists in continuous_states.
• Check its type (e.g., list, np.ndarray) and convert

---

• Ensure all continuous_states values are convertible to np.ndarray and then convert them to np.ndarrays

---

• Validate n_choices matches choices length
  - If n_choices exists in model_params, ensure it equals the length of choices

---

• Enforce positive extra_wealth_grid_factor ?

---

• Add a check for tuning_params keys: If provided, validate their types

Implemented Checks for check_options_and_set_defaults (that are also tested)

Validation Checks

• Ensure options is a dictionary.
• Ensure options contains a state_space dictionary.
• Ensure state_space is a dictionary.
• Ensure state_space contains n_periods.
• Ensure n_periods is an integer.
• Ensure n_periods is greater than 1.
• Ensure choices in state_space is either a list, integer, or numpy array (if provided).
• Convert choices to a numpy array of type uint8 if present.

Default Setting

• Set default choices to a numpy array [0] of type uint8 if not provided.
• Set default tuning_params to an empty dictionary if not provided.
• Set default tuning_params["extra_wealth_grid_factor"] to 0.2 if not provided.
• Set default tuning_params["n_constrained_points_to_add"] based on the length of the wealth grid if not provided.
• Set model_params["n_choices"] based on the length of state_space["choices"] if not explicitly provided.

Logical Consistency

• Ensure model_params is a dictionary.
• Ensure options contains model_params.
• Validate tuning_params to ensure the extra wealth grid factor is large enough to cover the constrained wealth grid points

Grid Preparation

• Compute the number of wealth grid points (n_wealth_grid) from the continuous_states["wealth"] grid.
• Compute the total wealth grid size (n_total_wealth_grid) based on extra_wealth_grid_factor and n_constrained_points_to_add.
• Extract exogenous grids from continuous_states.

Secondary Continuous State

• Identify and handle the second continuous state (if continuous_states has more than one key).
• Compute the number of grid points for the second continuous state (n_second_continuous_grid).
