The coefficient of determination, often denoted as R², indicates the proportion of the variance in the dependent variable that can be explained by the independent variable(s) in a regression model. It ranges from 0 to 1, where a value closer to 1 suggests a strong explanatory power of the model, meaning that a significant portion of the variability in the outcome is accounted for by the predictors. Conversely, a value closer to 0 implies that the model does not explain much of the variance. However, R² does not indicate whether the relationship is causal or the appropriateness of the model.

What does the coefficient of -13644 tell us?
It tells you that something has a value of -13644.
How would one explain the coefficient of determination?
The coefficient of determination, is when someone tries to predict the outcome of the testing of a hypothesis, or their guess at to what will happen. It helps determine how well outcomes are determined beforehand.

What is the coefficient of determination if r 0.45?
The coefficient of determination, denoted as ( R^2 ), is calculated by squaring the correlation coefficient ( r ). If ( r = 0.45 ), then ( R^2 = (0.45)^2 = 0.2025 ). This means that approximately 20.25% of the variance in the dependent variable can be explained by the independent variable in the regression model.
If the r-value or correlation coefficient of a data set is negative the coefficient of determination is negative?
The coefficient of determination, denoted as (R^2), is always a non-negative value, regardless of whether the correlation coefficient (r-value) is negative or positive. The value of (R^2) indicates the proportion of the variance in the dependent variable that can be explained by the independent variable(s). While a negative r-value signifies an inverse relationship between the variables, (R^2) will still be a positive number, ranging from 0 to 1. Thus, a negative r-value does not imply a negative coefficient of determination.

Can A regression equation have a negative coefficient of correlation and a negative coefficient of determination?
It's not quite possible for the coefficient of determination to be negative at all, because of its definition as r2 (coefficient of correlation squared). The coefficient of determination is useful since tells us how accurate the regression line's predictions will be but it cannot tell us which direction the line is going since it will always be a positive quantity even if the correlation is negative. On the other hand, r (the coefficient of correlation) gives the strength and direction of the correlation but says nothing about the regression line equation. Both r and r2 are found similarly but they are typically used to tell us different things.
What is coefficient variation?
it is da same as coefficient of determination
What is coefficient of determination?
The coefficient of determination R2 is the square of the correlation coefficient. It is used generally to determine the goodness of fit of a model. See: http://en.wikipedia.org/wiki/Coefficient_of_determination for more details.
What does the coefficient of -13644 tell us?
It tells you that something has a value of -13644.
How do you determine coefficient of determination in excel?
= CORREL(x values,y values) ***clarification**** CORREL gives you the correlation coefficient (r), which is different than the coefficient of determination (R2) outside of simple linear regression situations.

What is numerical range of regression coefficient?
ɪf the regresion coefficient is the coefficient of determination, then it's range is between 0 or 1. ɪf the regression coefficient is the correaltion coefficient (which i think it is) the it must lie between -1 or 1.
What does the coefficient of determination explain in regression?
The coefficient, also commonly known as R-square, is used as a guideline to measure the accuracy of the model.
