Interpretation of the Predictive Index requires a trained PI analyst. You can find more information at www.predictiveresult.com.
PI stands for polarization index. We need to find IR value(IR1) for 1min and again find the IR value(IR2) for 10min. PI=IR2/IR1
When a wave traversing in a medium of less refractive index gets reflected at a medium of greater refractive index then wave undergoes a phase change of pi radians. But if the same reflection takes place as the wave traverses from a medium of greater refractive index to that of less refractive index, then no such phase change. The later reflection is known as total internal reflection. So as light traversing in air gets reflected at glass then phase change of pi radians occurs.
The primacy index can be calculated by the following formula: PI = C1/ (C1 + C2 + C3 + C4) * 100 PI = primacy index C1 = amount of people in the biggest city of the country C2 = amount of people in the second city of the country C3 = amount of people on the third city of the country C4 = amount of people in the fourth city of the country So you divide the population of the biggest city of the country by the sum of the four biggest cities in the country and multiply that by 100. If the PI is > or = to 50, then it is a primate city.
Yes, The PI and NPV always give the same decisions to accept or reject the projects. The Project's PI will be greater than 1.00 if the NPV is positive and PI will be less than 1.00 if the NPV is negative
From the technogym website: Performance index The Performance Index (Pi) was invented by Technogym to give a concise and easily comparable assessment of performance in a workout.A heart rate monitor must be worn for a minimum of 3 consecutive minutes to obtain a result. The index is based on a rating scale ranging from 0 to 99. The higher the rating, the greater your aerobic capacity. If your performance index increases, this means that you are exercising more intensely without increasing your heart rate. The criteria used to calculate the performance index makes it possible compare tests taken by people of different ages. The results can only be compared where the exercise duration and intensity are constant.
Predictive Index® is an assessment tool used by businesses for effective hiring and leadership development. It is not available for free online. Companies interested in trying PI® can ask their local representative for a demonstration. FMI: See PredictiveResults.com or contact PI Worldwide.
To answer your question, you simply make a "PI (π) sign using your index and middle finger on the recipients' (your brother's) palm. The pi sign should have roughly 1 inch space between the index and middle finger. Your ring and pink finger and thumb clasp the brother's index and middle finger, thus closing the pi sign (making both the index and middle finger to touch).

The NPV and PI both consider the time value of money and result in the same accept or reject decision when considering an independent project. The main difference between the two is that the PI may be useful in determining which projects to accept if funds are limited; however, the PI may lead to incorrect decisions when considering mutually exclusive investments
(pi)(1/pi)=1.4396 ...
the same as pi squared, which is 9.86960440109
