performance_mse: Mean Square Error of Linear Models
Description
Compute mean square error of linear models.
Usage
performance_mse(model, ...)
mse(model, ...)
Value
Numeric, the mean square error of model.
Arguments
model
A model.
...
Arguments passed down to lme4::bootMer() or boot::boot()
for bootstrapped ICC, R2, RMSE etc.; for variance_decomposition(),
arguments are passed down to brms::posterior_predict().
Details
The mean square error is the mean of the sum of squared residuals, i.e. it
measures the average of the squares of the errors. Less technically speaking,
the mean square error can be considered as the variance of the residuals,
i.e. the variation in the outcome the model doesn't explain. Lower values
(closer to zero) indicate better fit.
