how many variables are in the f statistic if a f statistic for the variable $y is significant how does f statistic work when a statistic is significant does it means that at least one of the levels of $x$ is linearly associated with the variable what does f statistic indicate what does an f statistic mean on regression tests what does f statistic mean what is the difference between an f statistic and a dummy variable why is the f test significant is the f statistic significant if the variable y is an outcome variable what variables does the f test represent what is the f for categorical variables what is the f statistic and what is the outcome what does F mean for multiple regression can multiple linear regression be compared against multiple categorical variables? what is the f statistic of regression if the f statistic is significant what is the outcome variable when a f statistic indicates a variable is an outcome variable, what is the significance of the statistic what does the f test mean in a regression what does f test mean in regression
