解释from scipy import stats的含义: 这条语句的含义是从scipy库中导入stats模块。scipy是一个用于数学、科学、工程领域的Python库,提供了大量的算法和函数来处理这些问题。通过from scipy import stats,你可以在Python脚本或交互式环境中直接使用stats模块提供的所有功能,而无需每次都指定完整的模块路径。 说明scipy是...
Ttest_indResult(statistic=-0.5627187905196761, pvalue=0.5739887114209541) 为了进行比较,我们可以使用 0 和 1 数组以及 scipy.stat.ttest_ind 来计算 t 统计量和 p 值,如上所述。 >>>group1 = np.array([1]*30+ [0]*(150-30))>>>group2 = np.array([1]*45+ [0]*(200-45))>>>ttest_ind(g...
