I get the results of the regression and I see that the two are correlated. Now, please guide me as to how I check if that correlation is also a causation with X aff...

Q: Is it a canonical elementary CA rule number?

LynnBackground Given an elementary cellular automaton rule number like, for example, 28 = 00011100… We can swap \$\color{red}{\text{the 2nd bit with the 5th bit}}\$ and \$\color{orange}{\text{the 4th bit with the 7th bit}}\$ to get a rule that acts the same way but mirrored horizontally. This gets ...

Q: Isn't reason a better translation of the Logos of John 1 than Word?

HermesJohn 1:1-3 1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things came into being through Him, and apart from Him nothing came into being that has come into being.

flemmingMy HVAC unit is constantly dripping water throughout the day. The dripping is coming from the PVC pipe that runs from the unit to a floor drain. Just over a week ago, I went to change my 3-month filter and it was soaked. Water seemed to also have leaked out of the unit and pooled up on that metal...

Q: Difference between Single-supply and Dual-supply CAN Transceiver

BouboubiI was about to choose the MCP2558FD CAN Transceiver for a personal project. I found on the datasheet the following diagram: If my understanding is good, I can use it as a dual-supply Transceiver. But I don't understand the physical difference on the CAN bus between single-supply and dual-supply....

Q: TMS9918 - why have separate data-in and data-out?

Valentino MiazzoUsually 8bit video chips interface with DRAM using: an address bus for rows and columns, a bidirectional data bus in the case of 1bit DRAM data-in and data-out pins are shorted on the same data line. The TMS9918 is different, address and data-in are multiplexed on the same bus data-out has its...

Q: Function Vector Space and operations defined on it

Simone ValigiHow is $(af)(x)$ different from $a(f(x))$, or how is $(f+g)(x)$ different from $f(x)+g(x)$? Intuitively, I understand that those relations need to be equal (because of the definition of vector sum and vector scaling), but I can't visually imagine with the functions from Calculus I. Ex: if I consi...

Q: Is it ok to select models using MASE and present the metric to client area as MAPE?

Guilherme ParreiraMy question follow this one. Metrics such as MASE and MSE have better properties than MAPE. However, MAPE has an excellent appeal for business areas, because it is easy to interpret and it is compared to the real data. Where I work, they use cMAPE to select the models and it is calculated as abs(...
