WebInterpreting STANDARD ERRORS, "t" STATISTICS, AND SIGNIFICANCE LEVELS OF COEFFICIENTS. Your regression output not only gives point estimates of the coefficients of the variables in the regression equation, it also gives information about the precision of these estimates. Under the assumption that your regression model is correct--i.e., that the … WebDec 1, 2024 · In regression, we normally have one dependent variable and one or more independent variables. Here we try to “regress” the value of the dependent variable “Y” with the help of the independent variables. In other words, we are trying to understand, how the value of ‘Y’ changes w.r.t change in ‘X’.
