Since the presence of noise in the data can significantly affect the quality of the forecasts, the aim of the article will be to evaluate the accuracy of predicting the time series filtered using the method of nearest neighbors. The test will be conducted on the basis of the financial time series, which consist of closing prices of companies listed on the Warsaw Stock Exchange and the daily exchange rates.
