R语言filein R语言filter函数编写MA(q)模型 一 移动平均 移动平均能消除数据中的季节变动和不规则变动。若序列中存在周期变动,则通常以周期为移动平均项数。移动平均法可以通过数据显示出数据长期趋势的变动规律。 R可用filter()函数做移动平均。用法:filter(data,filter,sides) 1、简单移动平均 简单移动平均就是将n...

A filter function is a higher-order function in Lisp that applies a test to each element of a list, removing those that fail the test and returning a list of the results. AI generated definition based on: Encyclopedia of Information Systems, 2003 ...
利用filter,可以巧妙地去除Array的重复元素: 1'use strict';23var4r,5arr = ['apple', 'strawberry', 'banana', 'pear', 'apple', 'orange', 'orange', 'strawberry'];6r = arr.filter(function(element, index, self) {7returnself.indexOf(element) ===index;8});9console.log(r.toString());...

Given the filter order n, the function returns b and a with r samples, where r = n+1 for lowpass and highpass filters and r = 2*n+1 for bandpass and bandstop filters. The transfer function is expressed in terms of b = [b1 b2 ⋯ br] and a = [a1 a2 ⋯ ar] as one of ...
