critical values for Johansen maximum eigenvalue statistic
[jc]=c_sja(n,p)
n: number of zero eigenvalues under the null hypothesis
p: order of time polynomial in the null-hypothesis
- p = -1, no deterministic part
- p = 0, for constant term
- p = 1, for constant plus time-trend
- p > 1 returns no critical values
jc: a (3x1) vector of percentiles for the maximum eigenvalue statistic for [90% 95% 99%]
