The procedure is done as follows: Step 1: estimate an unrestricted VAR involving potentially non-stationary variables; Step 2: Test for cointegration using Johansen test; Step 3: Form and analyse the VECM. An example of ECM. The idea of cointegration may be demonstrated in a simple macroeconomic setting.
HHG process can be very easily as well as intuitively explained by a simple three-step model originally proposed by Paul Corkum in 1993. Step 1: The outermost electron undergoes tunnel ionization upon interaction with the ultrashort laser pulse. Step 2: This tunnel ionized electron undergoes acceleration under the effect of laser pulse electric ...
The Parks–Bielschowsky three-step test, also known as Park's three-step test or Bielschowsky head tilt test, is a method used to isolate the paretic extraocular muscle, particularly superior oblique muscle and trochlear nerve (fourth cranial nerve), in acquired vertical double vision. It was originally described by Marshall M. Parks.

Surgery or special glasses (prisms) may be advised if there is no recovery in 6 to 12 months. If diplopia turns out to be intractable, it can be managed as last resort by obscuring part of the patient's field of view. This approach is outlined in the article on diplopia occurring in association with a condition called horror fusionis. See also
Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. [1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home.
Endoscopic laser cordectomy, also known as Kashima operation, [1] is an endoscopic laser surgical procedure performed for treating the respiratory difficulty caused as a result of bilateral abductor vocal fold paralysis. Bilateral vocal fold paralysis is basically a result of abnormal nerve input to the laryngeal muscles, resulting in weak or ...
The Šidák correction is derived by assuming that the individual tests are independent. Let the significance threshold for each test be ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant).
