Mathematical Problems in Engineering and the authors have retracted the article titled “A Bimodel Algorithm with Data-Divider to Predict Stock Index” [1] due to errors identified in the figures and data by the authors.

The programs used were modified by the authors during the study, and it was identified that Figures 2 and 3 in the published article do not correspond with the test sets. Figures 4, 5, 8, and 9 are incorrect as a result of this error.

The authors apologized and requested the retraction of the article, which has been in agreement with the editorial board.
