图表分析术语:(1)Means 平均值(2)SD:Standard Deviations 标准差(3)SS,sum of squares of deviation from mean 离均差平方和(4)DF:degree of freedom 自由度(5)MS:mean square 均方(6)SIG=significance,意为“显著性”sig > 0.05 则方差分析的结果应该值得信赖sig值≤0.05 则方差分析的结果也值得怀疑注意,...

aArithmetic means+standard deviation are presented throughout the paper. All data were tested for normal distribution with the ShapiroeWilk test. Statistical significance between different means was tested with Duncan’s multiple range test.Statistical analyses were calculated with SAS 6.04 software (SAS...
Please see the example below: use http://www.stata-press.com/data/r11/ibm tsset t generate ibmadj = ibm - irx generate spxadj = spx - irx now I want to generate means and standard deviation of both ibmadj and spxadj with window of 200 days. I looked in the Stata manual, it ...
