The fan and motor for the blower is usually under dash on the passenger side behind the glove box. Most of the time it can be removed by removing the bolts (should be 10mm) from the bottom of the dash area. I did not get the model of your vehicle, but sometimes you will need to remove the glove box to access.
In statistics, the coefficient of determination, denoted R2 or r2 and pronounced R squared, is a number that indicates the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
Variance is non-negative because the squares are positive or zero. The variance of a constant random variable is zero, and if the variance of a variable in a data set is 0, then all the entries have the same value. Variance is invariant with respect to changes in a location parameter.That is, if a constant is added to all values of the variable, the variance is unchanged.ere Cov(â, â) is the covariance, which is zero for independent random variables (if it exists). The formula states that the variance of a sum is equal to the sum of all elements in the covariance matrix of the components.
