How to interpret results of Johansen Test? @techpaisa you have to successively test, the first one is null: r=0 against r>0. in your case you reject at 99% if your test (12.88) >24.60. If this was true you would then test r=1 against r>1 : 2.46>12.97. if you reject that then you can conclude that r=2. You do not need to know the degree of freedom as the critical values are tabulated |

How to model time series of illiquid stocks - 400 observations (transactions) per 8 hours? This is not specific of illiquid securities but you won't get any single model that answers your question. You will need to ask yourself what is the final aim of your model. This will highly depend on what you want to do with it. If it's algo trading the first most important characteristic will be out sample predictive performance. If you want to build a pricer you will probably be more interested in the way it estimates it's volatility. |

Measuring co-movement at non-constant intervals Could you be clearer? Are you talking about irregularly spaced time series? |

Is there a closed-form solution for the partial autocorrelation function of a Markov regime-switching process? +1 for simplicity. Are you planning on applying this model to financial time series prediction? |

How to build a mean reverting basket? @VictorP: Your question is very similar to the one asked just yesterday by Quant Guy. The paper I cite in my answer is an attempt to build such portfolios. There is also a post on the tr8dr blog related to that matter. You can find it by searching "cointegration clusters Tr8dr" on google. |

Two prices pass the cointegration test but there is a trend. How to check stationarity? You can include a constant and a deterministic trend in your initial regression. You then test for the presence of the trend (ie the significance of the parameter before the trend term). |

Variable Selection in factor models You should be concerned with correlation among your inputs or at least used technics such as ridge regression when estimating your model. |
