Calculate the case-deletion coefficience of the MLE estimation of quantile regression

1	ALDqr_case_deletion(y, x, tau, error, iter)

`y`	Response variable in quantile regression model
`x`	Predictors in quantile regression model. Note that: x is the independent variable matrix which including the intercept. That means, if the dimension of independent variables is p and the sample size is n, x is a n times p+1 matrix with the first column being one.
`tau`	Quantile
`error`	The EM algorithm accuracy of error used in MLE estimation
`iter`	The iteration frequancy for EM algorithm used in MLE estimation
