The maximum kernel likelihood estimator is defined to be the value \(\hat \theta\) that maximizes the estimated kernel likelihood based on the general location model,
$$f(x|\theta) = f_{0}(x - \theta).$$
This model assumes that the mean associated with $f_0$ is zero which of course implies that the mean of
\(X_i\) is \(\theta\). The kernel likelihood is the estimated likelihood based on the above model using a kernel density estimate, \(\hat f(.|h,X_1,\dots,X_n)\), and is defined as
$$\hat L(\theta|X_1,\dots,X_n) = \prod_{i=1}^n \hat f(X_{i}-(\bar{X}-\theta)|h,X_1,\dots,X_n).$$
The resulting estimator therefore is an estimator of the mean of \(X_i\).
