chi2test
给定一批的样本,当然这些样本间必须相互独立。如果Q > chi2(p, nu),假设拒绝,否则通过。
ARGUMENTS:
x Absolut numbers.
p The prob ability value, calculated from Q.
Q The resulting Q-value.(A given batch of samples, of course, among these samples must be independent of each other. If Q> chi2 (p, nu), the assumption that refuse, or else through. ARGUMENTS: x Absolut numbers. P The prob ability value, calculated from Q. Q The resulting Q-value.)
