Predicting the Type of Auditor Opinion: Statistics, Machine Learning, or a Combination of the Two?
Description of this data
The data from 13,561 complete sets of annual financial statements for 4,701 companies are combined with the data from the corresponding audit reports, forming an unbalanced panel data set.
The client companies included in the sample represent a supermajority of medium- and large-sized companies registered in the Republic of Serbia.
The information on the auditor firm name and the type of audit opinion is hand-collected from the audit reports issued by 64 audit firms (Big 4 plus 60 other audit firms), which, again, represents a supermajority of all the auditor firms registered in this country.
To the best of our knowledge, this is the largest data set used in the literature devoted to predicting the type of audit opinion.
In the total sample of audit opinions (13,561), the following frequencies of the four main types of audit opinions are observed: adverse opinion (71), disclaimer of opinion (644), qualified opinion (3,706), and unqualified opinion (9,140).
