2024/3/5 -ΣXΣY =add all of X together for the first value, all of Y together for the second value, then multiply together.
2018/8/22 -but of course you want to prove the opposite implication. A shorter proof would be to use the triangle inequality; |x−y|=|x+(−y)|≤|x|+|−y|=|x|+| ...
MX is the mean of X, MY is the mean of Y, sX is the standard deviation of X, sY is the standard deviation of Y, and r is the correlation between X and Y.
y=xz+s y = x z + s. Step 1. Rewrite the equation as xz+s=y x z + s = y . xz+s=y x z + s = y. Step 2. Subtract s s from both sides of the equation. xz=y−s x z = ...
