On the distribution of the coefficients of variation of the raw silk size in electronic testing
Random sampling Continuous sampling Distribution of the coefficient of variation Equivalent sample
2009/3/17
For the electronics testing of the raw silk size, we discussed the distribution characteristic of coefficients of variation of raw silk size. As we know, the size of the raw silk tested with electroni...
