coef.crq {crq} | R Documentation |
This function extracts linearly interpolated coefficients at specified quantiles from an object of class crq.
## S3 method for class 'crq': coef(object, taus = 1:4/5, ...)
object |
An object of class "crq" produced by crq |
taus |
A vector of quantiles at which to evaluate the coefficients |

Other arguments passed for printing, etc. |
Extracts coefficients by linear interpolation.
A matrix with the estimated coefficients at each of the chosen quantiles. The last row is the conditional quantile function evaluated at the mean design point, i.e. Qbar = xbar ' betahat (tau).
