What is peak analysis?
Peak Analysis is a program written in IDL to analyze one dimensional spectra using a number of model fit functions (including the effects of instrumental resolution). Once you have specified the position and amplitude of the function then you adjust the width (again, only for the model functions with peaks of course).
What is a peak in a graph?
A peak of a distribution is a “bump” or high point in a graph. In statistics, the peaks are more formally called modes; The data count is higher in these areas than in any other parts of the graph. In calculus, the peaks are often called local maximums or global maximums. A unimodal distribution has one peak.
What is a peak and a trough?
The trough level is the lowest concentration in the patient’s bloodstream, therefore, the specimen should be collected just prior to administration of the drug. The peak level is the highest concentration of a drug in the patient’s bloodstream.
What is peak detection algorithm?
Abstract. A new automatic peak detection algorithm is developed and applied to histogram-based image data reduction (quantization). The algorithm uses a peak detection signal derived either from the image histogram or the cumulative distribution function to locate the peaks in the image histogram.
What does peak mean in data?
Explanation: A peak in the data shows that you have a large number of respondents or a high rate at a certain point along your x axis. You can have multiple peaks in your data and they can be gradual or sharp. Data that is more peaked is data that has a sharper peak compared to data with a more gradual slope.
What does peak mean in math?
An observation in an ordered series is said to be a “peak” if its value is greater than the value of its two neighbouring observations.
What is peak finding?
What is Peak-Finding? Imagine you have a set of numbers, these numbers are stored in a one dimensional array; hence a normal array. Now you want to find one of the elements where the element peaks. Notice that we don’t want to find the highest peak, we just want to find a peak.
How do you find the peak of a data?
A common requirement in scientific data processing is to detect peaks in a signal and to measure their positions, heights, widths, and/or areas. One way to do this is to make use of the fact that the first derivative of a peak has a downward-going zero-crossing at the peak maximum.
