## Probability density function

The function that describes the change of certain realizations for a continuous random variable.

## Probability Function

In statistics, a measure of the probable distribution of some random variable. When plotted on a chart, the area under the graph represents the probable values of the random variable. It is used in foreign exchange and equities as a means of assessing probable future market trends.

From Figure 6(a) we can see that as the traditional timing distribution scheme does not have the vehicle traffic density changes in adaptive control, the street2 traffic density curve has a regular fluctuation with the traffic light.

To simulate the galactic density curve, we need in addition to a cosmological model, two other behaviors: the galactic density versus redshift and the relationship between the average galactic radius and redshifts.
These images were sub-divided into fields of constant size of which porosity was determined, allowing construction of the probability density curve. The shape of this curve depends not only on technical parameters, but also on field size.
Van Deusen found when assuming a power spectral density curve proportional to negative two power, that the detrending parameter (4) needed could be related to the variance of the data for cross-country or natural terrain.
For an exponential distribution, the probability density curve is a function of a single parameter.
Specifically, a peak on the crosslink density curve (inverse capacitance curve) is an indicator of complete cure under the sensor window.
After the posterior probability distribution is estimated, the probability of coexistence can be calculated as the volume under the posterior probability density curve where [[Delta].sub.1] [less than] 0 and [[Delta].sub.2], [less than] 0, since this is the parameter space where the condition for coexistence is met.
At this point, the elastic energy was necessary for release for two or more times, which again caused a decrease of the elastic energy density curve after a certain period of stability.
Fuel cell performance can be represented by a polarization curve, that is, the cell potential versus current density curve, which reflects the fuel cell activation loss in the low current density range, the ohmic losses in the intermediate current density range, and the concentration loss in the high current density range.
CMYK Optimizer version 3 with pressSign press calibration option allows prepress operators to use tonal value increase, neutral print density curve, or ICC-based press calibration, ensuring that output files are optimized to standardized printing presses, resulting in improved quality and shorter makeready.
