# ncointtest_matlab
ncointtest is a MATLAB implementation of the non-coointegration test, as developed by Souza et al (2018). The function takes five arguments:x and y, which are two time series, without missings,
d, which is the order of integration of the two time series; b, which is the bandwidth in the test and it is a percentage of the number of observations, with n^b being the number of observations used in the test;
and r, which is the number of neighboring frequencies to be utilized in estimating the density spectral matrix..
