WebIn the first round of analysis, R-sq is 87.3%, R-sq(adj) is 85%, the p-values for both Age and Mileage are 0.118, and the p-value for Red is 0.002. VIF values are all below 10. WebR-squared is known as “multiple R”, and it is equal to the correlation between the dependent variable and the regression model’s predictions for it. (Note: if the model does not include a constant, which is a so-called “regression through the origin”, then R-squared has a different definition. See this pagefor more

WebFeb 26, 2024 · Near zero (the null hypothesis value), then your p-value will be high. The data you observe is very probable if the null is true. If your p-value is near 1, then the observed effect almost exactly equals the null hypothesis value. Far from zero (not close to the null hypothesis value), then your p-value will be low. WebAnswer (1 of 4): First, let me make it clear, there is no association between R-squared and P-value because they measure different things. R-square value tells you how much variation is explained by your model. R-square of 0.3 means that your model explains 30% of variation within the data.
