Residuals function in r

WebFig. 6.5, p. 217. First we use the coxph function to obtain a cox model object. Then we can apply the resid function to the cox model object and obtain the score residuals by specifying the option type to equal “score”. The object score is a matrix and the columns of the matrix are the score residuals for the predictors in the cox model.

WebDeviance residual. Usually, the deviance residual is preferable to the other types of residuals in the diagnostics of GLMs. In R, it’s simple to implement these different types of residuals using the ‘residuals’ function.

WebDescription. Returns sigma, which corresponds the estimated standard deviation of the residuals. This function extends the sigma () base R generic for models that don't have implemented it. It also computes the confidence interval (CI), which is stored as an attribute. Sigma is a key-component of regression models, and part of the so-called ... WebA data frame. add_residuals adds a single new column, .resid, to the input data. spread_residuals adds one column for each model. gather_predictions adds two columns .model and .resid, and repeats the input rows for each model.
