Percentile

Calculates the Adjusted R2 (adjr2) from observed values, predicted values and the number of model parameters.

##### Usage
adjr2(o, p, k)
##### Arguments
o

A numeric vector. Observed values.

p

A numeric vector. Predicted values.

k

A number. The number of parameters in the model. Note that k includes the intercept, so for example, k is 2 for a linear regression model.

##### Details

Interpretation: larger is better. Adjusted R2 (adjr2) punishes complexity of models; a larger number of parameters (k) means a smaller adjr2 value.
