Useful Commands

Bash

Display ANSI colors with their color-code.

function colormap() {
    range_start=${1:-1}
    range_end=${2:-255}

    for i in $(seq $range_start $range_end); do
        echo -en "\e[48;5;${i}m  ${(l:3::0:)i}  \e[0m "
        [[ $((i % 10)) -eq 0 ]] && echo
    done
    return 0
}

The colormap function will print the ANSI colors with codes in your terminal.

Introduction To Hypothesis Testing

Null V/S Alternative Hypothesis

Parameter	Null Hypothesis	Alternative Hypothesis
Definition	A null hypothesis is a statement in which there is no relation between the two variables.	An alternative hypothesis is a statement in which there is some statistical relationship between the two variables.
What is it?	Generally, researchers try to reject or disprove it.	Researchers try to accept or prove it.
Testing Process	Indirect and Implicit	Direct and Explicit
p-value	Null hypothesis is rejected if the p-value is less than the alpha-value; otherwise, it is accepted.	An alternative hypothesis is accepted if the p-value is less than the alpha-value otherwise, it is rejected.
Notation	\(H_0\)	\(H_1\)
Symbol	Used Equality Symbol (=, ≥, ≤)	Inequality Symbol (≠, <, >)
