Abstract: Let {Xn,n≥1}be a strict stationary sequence of mdependent random variables with probability density function f(x). Based on mdependent samples, the kernel estimator for f(x)is constructed, and with the application of the property of i.i.d.samples, the consistency in rorder mean, the pointwise strong consistencyand strong uniform consistency are shown under suitable conditions.

Key words: mdependent samples, density function, kernel est imator, property of consistency
