standard error and p-value for the estimated parameter in AR model

Dear All,

I used an  AR(1) model to explain the process of the stationary residual and have used an 'ar' command in R. From the results, i tried to extract the standard error and p-value for the estimated parameter, but unfortunately, i never find any way to extract  it from the output. 

What i did was, i assigned the residuals into the 'residual' object in R and used an 'ar' function as below. 

  

residual <- residuals
ar(residual, aic = TRUE,  method = "mle", order.max = 1) 
    

Could someone help me to extract the stadard error and the p-value for the estimated parameter, please?

Thank you

Fir
