查询词典 variance analysis

According to the statistic analysis of Prof. Amari on static recognition with neural networks, and introducing the concept of vector position stochastic variable of vector stochastic sequence, the stochastic variable is processed by DRNN. The relationship between input and output variance is analyzed. The stochastic analysis of dynamic identification is given, so as to explain the DRNN characteristics in recognition process.

第二，根据Amari教授对神经网络静态识别时的统计分析，引入矢量随机序列的矢量位置随机变量的概念，以该随机变量经过DRNN处理后，分析其输入与输出方差之间的关系，试给出了DRNN做动态识别时的统计分析，以从理论上说明DRNN在识别过程中的特性。

Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

材料与方法：搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变，以对侧正常乳腺腺体作为正常对照，采用横轴位的平面回波-扩散加权成像序列，TR=8400ms，TE=93.8ms，层厚=4mm，激励次数=2：视野=30×30cm，矩阵=128×128，ASSET=2，b值=0和1000s/mm~2；参考动态增强图像准确定位，测量病变区和对侧正常乳腺腺体的ADC值，应用t检验比较良、恶性病变及正常腺体ADC值的差异，采用接收者工作特征曲线(receiver operating characteristic curve，ROC)确定良恶性病变的ADC界值；根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组，比较ADC值在肿块和非肿块性病变中定性诊断的效能。

And these 6 influential factors were analyzed with the experiment by means of range, variance and regression analysis. During the analysis, the evaluation criteria were the acceleration of rolling rock movement and the restitution coefficient of collision velocity between rolling rock and slope surface.

在试验基础上，采用极差、方差和回归分析等手段，以滚石运动的加速度和滚石与坡面碰撞速度恢复系数作为评价指标，对影响滚石在斜坡上运动特征的6个因素进行分析。

There is not a significant difference in these groups by one-way analysis of variance. 2 Among 51 cases with lung cancer, 7 specimens showed malignant cells in bronchial lavages, including 4 cases in central lung cancer and 3 cases in peripheral lung cancer. Concordant results were observed in 20 cases. 6 specimens showed malignant cells on cytological analysis, and NMSP was positive in at least one gene tested. 14 samples did not show malignant cells on cytological analysis, and the NMSP results were correspondingly negative. The results of cytology and NMSP were discordant in 31 samples. 30 samples were cytologically negative, but NMSP positive in one or more genes. In addition, there was one case that the cytology was positive for malignant cells, but the NMSP was negative in all of the three gene tested.
