4、時(shí)，為初始參數(shù)，可取1或任意奇數(shù)。利用上式算出序列后再取 即為第個(gè)0,1 均勻分布的隨機(jī)數(shù)。2.2 平方取中法首先給出一個(gè)初始數(shù)，或稱種子。把這個(gè)數(shù)平方，然后取中間位的數(shù)，再放上小數(shù)點(diǎn)就得到一個(gè)隨機(jī)數(shù)。這個(gè)中間位的數(shù)再平方取中得到第二個(gè)隨機(jī)數(shù)。其遞推公式為： 其中，x0為2k位的非負(fù)整數(shù)，x表示取x的整數(shù)部分，NmodM為對N進(jìn)行模為M的求余運(yùn)算，即：3檢驗(yàn)方案3.1 分布均勻性檢驗(yàn)采用卡方分布檢驗(yàn)?？ǚ綑z驗(yàn)利用樣本統(tǒng)計(jì)量式中，Qi是第i組觀察到的次數(shù)，Ei是出現(xiàn)在第i組的期望次數(shù)，n是組數(shù)。 對均勻分布來說，當(dāng)各組尺寸相同時(shí)，每一組中數(shù)的期望次數(shù) Ei由下式給出: 式中，N是總觀察次數(shù)?？ǚ?/p>

5、樣本統(tǒng)計(jì)量分布漸近地服從自由度為 n-1 的卡方分布?？ǚ綑z驗(yàn)步驟如下：第一步：將0,1)區(qū)間分成 n-1個(gè)不相容的小區(qū)間 （i=1,2,n）；第二步：由均勻性假設(shè)， 落入第i個(gè)小區(qū)間 概率為1/n，計(jì)算 (i=1,2,m)，稱之為理論頻數(shù)；第三步：計(jì)算xi 序列落在區(qū)間 中的個(gè)數(shù)ni(i=1,2,m)，稱之為經(jīng)驗(yàn)頻數(shù)；第四步：由于樣本統(tǒng)計(jì)量漸近地服從自由度為n-1的卡方分布，對給定水平，查卡方分布表得臨界值：第五步：計(jì)算出卡方的值，如果,可以得出結(jié)論：經(jīng)驗(yàn)頻數(shù)與理論頻數(shù)之間沒有檢測出明顯的差異。如果，拒絕假設(shè)。3.2 分布獨(dú)立性檢驗(yàn)采用趨勢檢驗(yàn)（連貫性檢驗(yàn)）。設(shè)給定N個(gè)隨機(jī)數(shù) ，令 ，把 v

6、i按正負(fù)分為兩類，表示隨機(jī)數(shù)的增減及長度的變化規(guī)律，組成升降兩類連。用T表示一個(gè)隨機(jī)數(shù)序列的連的總數(shù)，當(dāng)獨(dú)立服從 U(0,1)分布時(shí)，有：，；統(tǒng)計(jì)量漸近地服從N(0,1)。于是，可以利用統(tǒng)計(jì)量T 對隨機(jī)數(shù)序列進(jìn)行檢驗(yàn)。4. 隨機(jī)變量產(chǎn)生算法4.1 正態(tài)分布：生成正態(tài)分布隨機(jī)數(shù)的具體算法如下：第一步：產(chǎn)生兩個(gè)獨(dú)立的均勻分布U(0，1)隨機(jī)數(shù)，；第二步：計(jì)算;第三步：返回，則 y就是正態(tài)分布隨機(jī)數(shù)。4.2 負(fù)指數(shù)分布：采用逆變換法生成負(fù)指數(shù)分布E()的隨機(jī)數(shù)的步驟：第一步：產(chǎn)生獨(dú)立的U(0,1)隨機(jī)數(shù)；第二步：令，i=1,2,n，則 就是負(fù)指數(shù)分布E()的隨機(jī)數(shù)。4.3 愛爾郎分布：Erlang分

7、布的隨機(jī)數(shù)生成方法： 第一步：產(chǎn)生獨(dú)立的U(0，1)隨機(jī)數(shù)隨機(jī)數(shù) x1，x2，xi，xN； 第二步：令x = x1+x2+xi+xN，i=1,2,n； 第三步：令y = -(1/)ln(x) ，則y就是n階愛爾朗分布的隨機(jī)數(shù)4.4 威布爾分布：采用逆變換法生成威布爾分布W(,)的隨機(jī)數(shù)的步驟：第一步：產(chǎn)生獨(dú)立的U(0,1)隨機(jī)數(shù)；第二步：令，i=1,2,n，則就是威布爾分布W(,)的隨機(jī)數(shù)。4.5 均勻分布:采用逆變換法生成U(a,b) 隨機(jī)數(shù)的步驟：第一步：產(chǎn)生獨(dú)立的U(0,1)隨機(jī)數(shù)；第二步：令，則就是U(a,b)的隨機(jī)數(shù)5. 程序代碼5.1 MyJFrame_1.javaimport j
