        <p>Проанализированы методы обработки статистических данных о периодическом процессе методом наименьших квадратов с использованием функций Бесселя и рядов Фурье. Предложен несложный метод аппроксимации, в котором выбор значения периода колебания осуществляется, исходя из минимума оценки погрешности.</p>

        <p>In the article the methods of processing of statistical data about periodic process by the least squares method with usage of Bessel functions and Fourie numbers are analyzed. The simple method for approximation with a choice of the fluctuation period, proceeding from a minimum of the estimated error is offered.</p>
