  2. Log-normal distribution - Wikipedia

    en.wikipedia.org/wiki/Log-normal_distribution

    In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed.Thus, if the random variable X is log-normally distributed, then Y = ln(X) has a normal distribution.

  3. RAWGraphs - Wikipedia

    en.wikipedia.org/wiki/RAWGraphs

    The project was started in 2013 by a group of researchers of Politecnico di Milano [2] [3] with the original name of "RAW". Version 1.0.0 was released in 2014. Version 1.0.0 was released in 2014. In the same year the tool won the "Most Beautiful" award at the Kantar Information is Beautiful Awards 2014 organized by David McCandless .

  4. Flow cytometry bioinformatics - Wikipedia

    en.wikipedia.org/wiki/Flow_cytometry_bioinformatics

    The complexity of raw flow cytometry data (dozens of measurements for thousands to millions of cells) makes answering questions directly using statistical tests or supervised learning difficult. Thus, a critical step in the analysis of flow cytometric data is to reduce this complexity to something more tractable while establishing common ...

  5. Compositional data - Wikipedia

    en.wikipedia.org/wiki/Compositional_data

    In demography, a town may be a compositional data point in a sample of towns; a town in which 35% of the people are Christians, 55% are Muslims, 6% are Jews, and the remaining 4% are others would correspond to the quadruple [0.35, 0.55, 0.06, 0.04]. A data set would correspond to a list of towns.

  6. Flow Cytometry Standard - Wikipedia

    en.wikipedia.org/wiki/Flow_Cytometry_Standard

    Flow cytometry data is typically saved for analysis in the form of an array, with fluorescence and scatter channels represented in columns, and individual "events" (most of which are cells) forming the rows. The number of events acquired from each sample usually ranges between the low thousands and the low millions.

  7. Raw data - Wikipedia

    en.wikipedia.org/wiki/Raw_data

    Raw data is a relative term (see data), because even once raw data have been "cleaned" and processed by one team of researchers, another team may consider these processed data to be "raw data" for another stage of research. Raw data can be inputted to a computer program or used in manual procedures such as analyzing statistics from a survey.

  8. Data transformation (statistics) - Wikipedia

    en.wikipedia.org/wiki/Data_transformation...

    The upper plot uses raw data. In the lower plot, both the area and population data have been transformed using the logarithm function. In statistics , data transformation is the application of a deterministic mathematical function to each point in a data set—that is, each data point z i is replaced with the transformed value y i = f ( z i ...

  9. MA plot - Wikipedia

    en.wikipedia.org/wiki/MA_plot

    The plot visualizes the differences between measurements taken in two samples, by transforming the data onto M (log ratio) and A (mean average) scales, then plotting these values. Though originally applied in the context of two channel DNA microarray gene expression data, MA plots are also used to visualise high-throughput sequencing analysis ...
