The higher the COP ratio, the more efficient the equipment is at providing heating. The Coefficient of performance is most used to indicate the performance of an HVAC unit when it is in heating mode. Similar to EER, it is a ratio of inputs vs outputs; if a unit has a COP of 4, ...
Definition: The coefficient of determination, often referred to as r squared or r 2, is a dependent variable’s percentage of variation explained by one or more related independent variables. In other words, it’s a statistical method used in finance to explain how the changes in an independen...
In the model, the percentage of women directors is taken as BGD measures and value-added intellectual coefficient as an IC performance measure, considering governance and corporate performance measures. Findings The authors find a significant impact of BGD on FP. In particular, the results suggest:...
Definition:The coefficient of variation, or CV, is a statistical measurement that shows how a set of data points is distributed around the mean of the set. In other words, a set of data is graphed and the CV equation is used to measure the variation in points from each other and the m...
When an object is put under the changing temperature conditions, the length, the area or the volume change with the temperature. With increasing the temperature of the object then the kinetic energy of the molecules increases and this produces the se...
The Pearson coefficient, also known as the Pearson correlation coefficient or Pearson’s r, is a statistical measure that quantifies the strength and direction of the linear relationship between two variables. It is a value between -1 and 1, where -1 indicates a perfect negative correlation, ...
To find the efficiency of a Carnot engine working between the ice point and steam point, we can follow these steps:1. Identify the Temperatures: - The ice point corresponds to a temperature of 0°C, which is equivalent to 2
A correlation coefficient is the statistical measure that will tell us whether there is a relationship between our two variables of interest, and if there is one, how strong that relationship is. The value of the correlation coefficient, ϝ (rho), ranges from -1 to +1. The closer to -...

Nonetheless, there are insufficient studies examining how to efficiently and effectively leverage big data analytics capability (BDAC) to improve organizational agility, innovation, and firm performance. Particularly, there is a gap in the literature on the impact of big data in influencing firm ...
