  2. Propensity score matching - Wikipedia

    en.wikipedia.org/wiki/Propensity_score_matching

    Kernel matching: same as radius matching, except control observations are weighted as a function of the distance between the treatment observation's propensity score and control match propensity score. One example is the Epanechnikov kernel. Radius matching is a special case where a uniform kernel is used.

  3. Matching (statistics) - Wikipedia

    en.wikipedia.org/wiki/Matching_(statistics)

    Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).

  4. Taxation in Pakistan - Wikipedia

    en.wikipedia.org/wiki/Taxation_in_Pakistan

    Taxation in Pakistan is a cornerstone of the country’s economic framework, managed by the Federal Board of Revenue (FBR). The FBR operates under the Ministry of Finance and is tasked with formulating tax policies, collecting federal taxes , and ensuring compliance with tax laws.

  5. Kernel density estimation - Wikipedia

    en.wikipedia.org/wiki/Kernel_density_estimation

    Kernel density estimation of 100 normally distributed random numbers using different smoothing bandwidths.. In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights.

  6. Goods and Services Tax (India) - Wikipedia

    en.wikipedia.org/wiki/Goods_and_Services_Tax_(India)

    The purpose of HSN codes is to make GST systematic and globally accepted. The Harmonized system of Nomenclature (HSN) code is used for classifying goods under the Goods and Services Tax (GST) in India. The HSN code is a six-digit code that uniquely identifies a product.

  7. Gillespie algorithm - Wikipedia

    en.wikipedia.org/wiki/Gillespie_algorithm

    Partial-propensity formulations, as developed independently by both Ramaswamy et al. (2009, 2010) and Indurkhya and Beal (2010), are available to construct a family of exact versions of the algorithm whose computational cost is proportional to the number of chemical species in the network, rather than the (larger) number of reactions.

  8. Histogram matching - Wikipedia

    en.wikipedia.org/wiki/Histogram_matching

    An example of histogram matching In image processing , histogram matching or histogram specification is the transformation of an image so that its histogram matches a specified histogram. [ 1 ] The well-known histogram equalization method is a special case in which the specified histogram is uniformly distributed .

  9. Loss functions for classification - Wikipedia

    en.wikipedia.org/wiki/Loss_functions_for...

    Given the binary nature of classification, a natural selection for a loss function (assuming equal cost for false positives and false negatives) would be the 0-1 loss function (0–1 indicator function), which takes the value of 0 if the predicted classification equals that of the true class or a 1 if the predicted classification does not match ...
