In this folder, The estmate_quality_m.m and the estmate_quality_mv.m are used to estimate the mean function and variance function.
Other codes will be called by this two main functions.

estmate_quality_m.m: to estimate the mean function.
estmate_quality_mv.m: to estimate the variance function.
Cross_V_LK.m: to select bandwith for local linear kernel method.
Cross_V_EM.m: to select bandwith for our proposed method.
Cross_V_LK_Li.m: to select bandwith for Li's (2011) proposed method.
.m: to eastimate the mean function at x0 by using the estimator (3) in our paper.
getdata.m, getdatatime.m: to get data from the raw data saved in specified address.
LK.m: to eastimate the mean function at x0 by using local linear kernel method.
LK_Li.m: to eastimate the mean function at x0 by using Li's (2011) proposed method.
LS_PHI.m: to compute the coefficient of AR(1) model
Weight_1_i.m: to compute the W_i in (3) of our paper.
