6 1 $begingroup$ I have a linear regression model for a dependent variable $Y$ based on two independent variables, $X1$ and $X2$ , so I have a general form of a regression equation $Y = A + B_1 cdot X_1 + B_2 cdot X_2 + epsilon$ , where $A$ is the intercept, $epsilon$ is the error term, and $B_1$ and $B_2$ are the respective coefficients of $X_1$ and $X_2$ . I perform a multiple regression with software (statsmodel in Python) and I get coefficients for the model: $A = a, B_1 = b_1, B_2 = b_2$ . The model also gives me $p$ values for each coefficient: $p_a$ , $p_1$ , and $p_2$ . My question is: What is the null hypothesis for those individual $p$ values? For example, to obtain $p_1$ I know that the null hypothesis entails a 0 coefficient for $B_1$ , but what about the other variables? In other words, I...
