  2. Peristimulus time histogram - Wikipedia

    en.wikipedia.org/wiki/Peristimulus_time_histogram

    The peristimulus time histogram is sometimes called perievent time histogram, and post-stimulus and peri-stimulus are often hyphenated. The prefix peri, for through, is typically used in the case of periodic stimuli, in which case the PSTH show neuron firing times wrapped to one cycle of the stimulus.

  3. Scott's rule - Wikipedia

    en.wikipedia.org/wiki/Scott's_Rule

    Scott's rule is a method to select the number of bins in a histogram. [1] Scott's rule is widely employed in data analysis software including R, [2] Python [3] and Microsoft Excel where it is the default bin selection method. [4]

  4. Earth mover's distance - Wikipedia

    en.wikipedia.org/wiki/Earth_mover's_distance

    The EMD is widely used in content-based image retrieval to compute distances between the color histograms of two digital images. [citation needed] In this case, the region is the RGB color cube, and each image pixel is a parcel of "dirt".

  5. Cumulative frequency analysis - Wikipedia

    en.wikipedia.org/wiki/Cumulative_frequency_analysis

    Histogram derived from the adapted cumulative probability distribution Histogram and probability density function, derived from the cumulative probability distribution, for a logistic distribution. The observed data can be arranged in classes or groups with serial number k. Each group has a lower limit (L k) and an upper limit (U k).

  6. First-hitting-time model - Wikipedia

    en.wikipedia.org/wiki/First-hitting-time_model

    The first hitting time is defined as the time when the stochastic process first reaches the threshold. It is very important to distinguish whether the sample path of the parent process is latent (i.e., unobservable) or observable, and such distinction is a characteristic of the FHT model. By far, latent processes are most common.

  7. Umbrella sampling - Wikipedia

    en.wikipedia.org/wiki/Umbrella_sampling

    where () is the free-energy profile of the unbiased system, and () is the free-energy profile calculated for the biased, umbrella-sampled system. Series of umbrella sampling simulations can be analyzed using the weighted histogram analysis method (WHAM) [ 2 ] or its generalization. [ 3 ]

  9. Plotting algorithms for the Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Plotting_algorithms_for...

    The top row is a series of plots using the escape time algorithm for 10000, 1000 and 100 maximum iterations per pixel respectively. The bottom row uses the same maximum iteration values but utilizes the histogram coloring method. Notice how little the coloring changes per different maximum iteration counts for the histogram coloring method plots.
