The changes of conditional active avoidance response was tested by shuttle-box following forebrain ischemia/ reperfusion. 穿梭箱实验法观察大鼠前脑缺血/再灌流后条件性主动回避反应的变化。
Study on Performance Evaluation of Security Investment Based on the Conditional Asymmetric Response Model 基于条件非对称反应模型的证券投资基金表现实证研究
Operant conditional response is a core concept of the famous American psychologist Skinner's Neo-behaviorism theory. 操作性条件反射是美国著名心理学家斯金纳①新行为主义学习理论中的一个核心概念。
Based on the EM algorithm and conditional expectation of the complete-data log-likelihood function, this paper develops the local influence analysis of the zero inflated poisson regression models under the the case-weights, perturbation of explanatory variables and response, respectively, and the corresponding diagnostics statistics are obtained. 基于EM算法和完全数据对数似然的条件期望,分别研究了ZIP回归模型在加权扰动、解释变量扰动和响应变量扰动下的局部影响诊断问题,得到了相应的诊断统计量。
Methods CCK was injected into medial posterior nucleus accumbens of rats. The effects of CCK on discrimination learning ( DL) and conditional avoidance response ( CAR) were studied in the three-panel runway test in rats. 方法采用行为和脑核团内微量注射相结合的方法,利用三等分辐射式迷宫模型观察大鼠伏核中胆囊收缩素对分辨学习(DL)和条件性回避反应(CAR)的影响。
The conditional fluctuation of stock day turn in Shanghai stock markets were described and tested by using many asymmetric GARCH models. After analyzing the information response curves, it was found that the stock price fluctuation in Shanghai stock markets showed its asymmetry obviously. 通过利用多种非对称性GARCH模型,描述和检验了沪市股票日收益率序列的条件波动性,并通过对股票市场信息影响曲线的分析,发现沪市股票价格波动中存在显著的非对称性反应。
Quantile regression method is a regression technique based on minimization problem to obtain sample quantile. The approach can capture systematic influences of covariates on the location, scale and shape of the conditional distribution of the response. 分位回归方法通过解最优化问题来实现对变量样本分位数的估计,它可以刻画协变量对响应变量条件分布位置,尺度和形状的影响。
