auto_test — build specification tests function and vector of names
[test_func,name_test]=auto_test(auto_ names,auto_ltest,nobs)
auto_names = the tlist that associates a name to each specification test function
auto_ltest = the list of options provided by the user (default: an empty list)
nobs = # of observations
test_func = the function which gathers the specification tests used by automatic()
name_test = the name of the specification tests which will be used for the printings
[func,names] = auto_test('test=arlm(6),jbnorm,chowtest(0.8),myautocor(5)') //creates a function that performs the Breusch and Pagan test with 1 to 6 lags, the Jarque and Bera normality test, the Chow stability test with a break at 80% of the sample and the matrix of corresponding names. [test_func,m2prt_test]=auto_test(grocer_ltest) // This example is an application of auto_test in function automatic.
