Area under the curve (AUC) is the area under the plasma concentration-time plot . One application of AUC is to compare AUCs from lead series analogs, dosed in the same way, which provides a means to select the compounds that produce the highest exposure levels, lowest clearance, or highest bioavailability.
Why do we need to find the area under a curve?
It just so happens to be that the two are the same thing; the area represents the change in velocity . This is one example of how the integral can tell you more than just the area under the graph.
What does the area under the curve tell us?
A common use of the term “area under the curve” (AUC) is found in pharmacokinetic literature. It represents the area under the plasma concentration curve, also called the plasma concentration-time profile. ... The AUC is a measure of total systemic exposure to the drug.
What is the area under the normal curve?
Probability and the Normal Curve
The normal distribution is a continuous probability distribution. This has several implications for probability. The total area under the normal curve is equal to 1 . The probability that a normal random variable X equals any particular value is 0.
What does the area under the line represent?
The area under a speed-time graph represents the distance travelled . ... A horizontal line on a speed-time graph represents a constant speed. A sloping line on a speed-time graph represents an acceleration.
How do you find area under the curve?
The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b , integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.
How do you find the area under the z-score?
To find the area between two negative z scores we must first find the area (proportion of the SND) to the left of the lowest z-score value and the area (proportion of the SND) to the right of the highest z-score value.
What does the area under the best fit line represent?
Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points . Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software.
What is difference between distance and displacement?
Distance is a scalar quantity that refers to “how much ground an object has covered” during its motion. Displacement is a vector quantity that refers to “how far out of place an object is”; it is the object’s overall change in position.
Why distance is area under velocity time line?
The area under a speed-time graph represents the distance travelled . This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area of the velocity time graph.
What is best fit algorithm?
What is Best Fit Algorithm? Best Fit is a memory management algorithm ; it deals with allocating smallest free partition which meets the requirement of the requesting process. ... So we will take the block size and process size and return the output of the process and which block is to be allocated to a process.
How do you explain a trend line?
A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price . Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction.
Are line of best fit and regression the same?
The regression line is sometimes called the “line of best fit” because it is the line that fits best when drawn through the points . It is a line that minimizes the distance of the actual scores from the predicted scores.
What is difference between distance and displacement with example?
| Distance Displacement | 2) It can never be negative or zero, always positive 2) It can be positive, negative or zero depending on the context. |

What are the similarities and differences between distance and displacement?
In physics, distance and displacement are used to indicate the length between two points . However, these two are not one and the same thing. While distance is the length of the actual path between two locations, displacement, on the other hand, is the length of the shortest path between two locations.
What are the three differences between distance and displacement?
| Distance Displacement | 1. It is the actual length of path followed by the body while moving between two positions. 1. It is the linear distance between the initial and final positions of a body. | 2. It has only magnitude – it is a scalar quantity. 2. It has both magnitude and direction – it is a vector quantity. |
