KOLMTEST

Codigo en RATS.

By: Luis Fernando Mejía y Diego Vasquez
Read abstract | Download Program

It computes the corresponding statistic for the KOLMOGOROV-SMIRNOV test of goodness of fit and displays the correponding critical value at different significance levels.

One of the most important uses of this test is to check for NORMALLY distributed disturbances (regression diagnostics) as pointed in Judge et al (1988).

Generally, the KOLMOGOROV-SMIRNOV statistic provides a way testing whether a set of observations come from some completely specified continuous distribution Fo(x). The KOLMOGOROV-SMIRNOV test has at least two major advantages over the chi-square test:

1.
It can be used with small sample sizes, where the validity of the chi-square and Jarque-Bera tests would be questionable.

2.

Often it appears to be a more powerful test than the chi-square test for any sample size.

PERRON

Codigo en RATS.

By: Diego Vasquez
Read abstract | Download Programa

It computes the augmented "PERRON" unit root test allowing under both null and alternative hypothesis for the presence of a one-time change in the level or in the slope of the trend function using three different linear regression models which are constructed by nesting the corresponding null and alternative hypothesis.

SPUNIT

Código en RATS.

By Diego Vasquez
Read abstract | Download Programa

It computes the "Schmidt-Phillips" test (TAU) for a unit root which is constructed considering the following parametrization -DGP-:

yt = psi + epsilon * trend + X(t), X(t) = betha * X(t-1) + e(t)

Under the assumption that 'e(t)' are iid N(0,sigma^2e) and the initial X(0) is taken as fixed.
