switchreg |
type=arg | Type of switching: simple exogenous (“simple”), Markov (“markov”). |
nstates=integer (default=2) | Number of regimes. |
heterr | Allow for heterogeneous error variances across regimes |
fprobmat=arg | Name of fixed transition probability matrix allows for fixing specific elements of the time-invariant transition matrix. Leave NAs in elements of the matrix to estimate. The element of the matrix corresponds to . |
initprob=arg (default=“ergodic”) | Method for determining initial Markov regime probabilities: ergodic solution (“ergodic”), estimated parameter (“est”), equal probabilities (“uniform”), user-specified probabilities (“user”). If “initprob=user” is specified, you will need to specify the “userinit=” option. |
userinit=arg | Name of vector containing user-specified initial Markov probabilities. The vector should have rows equal to the number of states; we expand this to the size of the initial lag state vector where necessary for AR specifications. For use in specifications containing both the “type=markov” and “initprob=user” options. |
startnum=arg (default=0 or 25) | Number of random starting values tried. The default is 0 for user-supplied coefficients (option “s”) and 25 in all other cases. |
startiter=arg (default=10) | Number of iterations taken after each random start before comparing objective to determine final starting value. |
searchnum=arg (default=0) | Number of post-estimation perturbed starting values tried. |
searchsds=arg (default=1) | Number of standard deviations to use in perturbed starts (if “searchnum=”) is specified. |
seed=positive_integer from 0 to 2,147,483,647 | Seed the random number generator. If not specified, EViews will seed random number generator with a single integer draw from the default global random number generator. |
Type of random number generator: improved Knuth generator (“kn”), improved Mersenne Twister (“mt”), Knuth’s (1997) lagged Fibonacci generator used in EViews 4 (“kn4”) L’Ecuyer’s (1999) combined multiple recursive generator (“le”), Matsumoto and Nishimura’s (1998) Mersenne Twister used in EViews 4 (“mt4”). |
optmethod = arg | Optimization method: “bfgs” (BFGS); “newton” (Newton-Raphson), “opg” or “bhhh” (OPG or BHHH), “legacy” (EViews legacy). BFGS is the default method. |
optstep = arg | Step method: “marquardt” (Marquardt); “dogleg” (Dogleg); “linesearch” (Line search). Marquardt is the default method. |
m=integer | Set maximum number of iterations. |
c=scalar | Set convergence criterion. The criterion is based upon the maximum of the percentage changes in the scaled coefficients. The criterion will be set to the nearest value between 1e-24 and 0.2. |
cov=arg | Covariance method: “ordinary” (default method based on inverse of the estimated information matrix), “huber” or “white” (Huber-White sandwich method). |
covinfo = arg | Information matrix method: “opg” (OPG); “hessian” (observed Hessian). (Applicable when non-legacy “optmethod=”.) |
nodf | Do not degree-of-freedom correct the coefficient covariance estimate. |
coef=arg | Specify the name of the coefficient vector (if specified by list); the default behavior is to use the “C” coefficient vector. |
s | Use the current coefficient values in “C” as starting values (see also
param). |
s=number | Specify a number between zero and one to determine starting values as a fraction of EViews default values (out of range values are set to “s=1”). |
showopts / ‑showopts | [Do / do not] display the starting coefficient values and estimation options in the estimation output. |
prompt | Force the dialog to appear from within a program. |
p | Print results. |
