Polynomial. truncate(size)[source]¶
Truncate series to length size.
Reduce the series to length size by discarding the high degree terms. The value of size must be a positive integer. This can be useful in least squares where the coefficients of the high degree terms may be very small.
| Parameters: | size : positive int The series is reduced to length size by discarding the high degree terms. The value of size must be a positive integer. |
|---|---|
| Returns: | new_series : series New instance of series with truncated coefficients. |
