How to interpret regression equations with logarithms, based on log difference being approximate to percentage change?

https://stats.stackexchange.com/q/199256

For a 1-unit increase in X, we expect an 8.3% increase in Y Not quite, because the calculation goes \ln(Y') = 1.7 + 0.083(X + 1) = (1.7 + 0.083X) + 0.083 = \ln(Y) + 0.083 so a 1-unit increase ...

Probability at least one, using correlation

https://math.stackexchange.com/q/1531035

What does the correlation coefficient of two events mean? Is it the correlation coefficient of their Bernoulli indicator random variables? Then \newcommand{\Chi}{{\raise{0.5ex}{\chi}}} \begin{align} \rho_{\!\lower{0.5ex}{A,B}} & = {\sf Corr}(\Chi_A, \Chi_B) \\[1ex] & = \dfrac{{\sf Cov}(\Chi_A, \Chi_B)}{\sqrt{\,{\sf Var}(\Chi_A){\sf Var}(\Chi_B)\,}} \\[1ex] & = \dfrac{{\sf E}(\Chi_A\Chi_B)-{\sf E}(\Chi_A){\sf E}(\Chi_B)}{\sqrt{\,({\sf E}({\Chi}_A^2)-{\sf E}({\Chi}_A)^2)\,({\sf E}({\Chi}_B^2)-{\sf E}({\Chi}_B)^2)\;}} \\[1ex] & = \dfrac{{\sf P}(A\cap B)-{\sf P}(A){\sf P}(B)}{\sqrt{\,({\sf P}(A)-{\sf P}(A)^2)\,({\sf P}(B)-{\sf P}(B)^2)\;}} \\[2ex] \therefore {\sf P}(A\cap B) & = {\sf P}(A){\sf P}(B)+ \rho_{\!\lower{0.5ex}{A,B}} \sqrt{\,{\sf P}(A)(1-{\sf P}(A))\,{\sf P}(B)(1-{\sf P}(B))\;} \end{align}

Interpreting the meaning of this partial derivative

https://math.stackexchange.com/q/2827514

You are correct. \dfrac{\partial W}{\partial v}=-0.5796\;\; means that the thermal sensation will decrease wrt the velocity at a rate of 0.5796\;\; while temperature is constant. the units of \dfrac{\partial W}{\partial v} ...

Result of 1+1 in odd digits number system [closed]

https://math.stackexchange.com/q/2826471

Here is a reasonable definition. Let's call the set X = \{0,1,3,5,7,9\}. \forall a,b\in (X\setminus \{0\}), you have a+b=0 and a+0=0+a=a. 0+0=0 That makes sense. Odd numbers add together to ...

'Strange' trigonometric roots of x^5-4x^4+2x^3+5x^2-2x-1 - could someone explain?

https://math.stackexchange.com/questions/1841710/strange-trigonometric-roots-of-x5-4x42x35x2-2x-1-could-someone-expla

Using the equality \cos(\pi \pm x)=-\cos(x) you get x_1=-\frac{\cos \frac{3 }{22} \pi}{\cos \frac{1}{22} \pi} \\ x_2=-\frac{\cos \frac{9}{22} \pi}{\cos \frac{3}{22} \pi} \\ x_3=-\frac{\cos \frac{15}{22} \pi}{\cos \frac{5}{22} \pi} \\ x_4=-\frac{\cos \frac{21}{22} \pi}{\cos \frac{7}{22} \pi} \\ x_5=-\frac{\cos \frac{27}{22} \pi}{\cos \frac{9}{22} \pi} ...
