Calculate The Error Bars For Your Marketing Funnel
The Central Limit Theorem (CLT) and the concept of standard error guides most calculations of error bars. But the CLT has a pitfall: it says it only applies when there are "a lot" of samples, but doesn't tell you how many samples. You may be thinking 30 samples is enough. You'd be dead-wrong in the case of a marketing funnel, which has binary outcomes. Try the tool.
NST0: Transfer color schemes from one image to another.
There are many ways to transfer the color palette from one image to another. I came up with one based on the concept of Neural Style Transfer. Specifically, I realized the RGB channels were also styles, and if I could get their pixel range to shift from [0, 255] to [-inf, +inf], I could use the AdaIN operation from the Xun Huang paper.
