Dana Quade in 1979 proposed a test that is often more powerful than the Friedman test. It also eliminates block differences but weights the raw data indicate possibly more marked treatment effects. Whereas the Friedman test is basically an extension of the sign test, the Quade test is effectively an extension of the Wilcoxon signed rank test and is equivalent to it when the treatments are two.

AM、DSB 调制及解调 用matlab产生一个频率为1Hz，功率为1的余弦信源m(t)，设载波频率ωc =10 Hz， m0 = 2 ,试画出： 􀁺 AM 及DSB 调制信号的时域波形； 􀁺 采用相干解调后的 AM 及DSB 信号波形； 􀁺 AM 及DSB 已调信号的功率谱； 􀁺 调整载波频率及 m0，观察分的AM 的过调与DSB 反相点现象。 􀁺 在接收端带通后加上窄带高斯噪声，单边功率谱密度0 n = 0.1，重新解调。 (AM, DSB modulation and demodulation Matlab produce a frequency for 1 Hz, power of 1 cosine source m (t), set the carrier frequency ω c = 10 Hz, M0 = 2, try drawing out: )
