Description:
 def check_keys_and_values_of_name_dictionary(names, specification_dict, num_alts):
 """ Check the validity of the keys and values in the names dictionary. Parameters names : OrderedDict, optional. Should have the same keys as `specification_dict`. For each key: - if the corresponding value in `specification_dict` is "all_same", then there should be a single string as the value in names. - if the corresponding value in `specification_dict` is "all_diff", then there should be a list of strings as the value in names. There should be one string in the value in names for each possible alternative. - if the corresponding value in `specification_dict` is a list, then there should be a list of strings as the value in names. There should be one string the value in names per item in the value in `specification_dict`. specification_dict : OrderedDict. Keys are a proper subset of the columns in `long_form_df`. Values are either a list or a single string, `"all_diff"` or `"all_same"`. If a list, the elements should be: - single objects that are within the alternative ID column of `long_form_df` - lists of objects that are within the alternative ID column of `long_form_df`. For each single object in the list, a unique column will be created (i.e. there will be a unique coefficient for that variable in the corresponding utility equation of the corresponding alternative). For lists within the `specification_dict` values, a single column will be created for all the alternatives within iterable (i.e. there will be one common coefficient for the variables in the iterable). num_alts : int. The number of alternatives in this dataset's universal choice set. Returns ------- None. """
