  2. Partial likelihood methods for panel data - Wikipedia

    en.wikipedia.org/wiki/Partial_likelihood_methods...

    Partial (pooled) likelihood estimation for panel data is a quasi-maximum likelihood method for panel analysis that assumes that density of given is correctly specified for each time period but it allows for misspecification in the conditional density of = (, …,) given = (, …,).

  3. Data collection system - Wikipedia

    en.wikipedia.org/wiki/Data_collection_system

    Data collection systems are an end-product of software development. Identifying and categorizing software or a software sub-system as having aspects of, or as actually being a "Data collection system" is very important. This categorization allows encyclopedic knowledge to be gathered and applied in the design and implementation of future systems.

  4. Confidence and prediction bands - Wikipedia

    en.wikipedia.org/wiki/Confidence_and_prediction...

    96% confidence bands around a local polynomial fit to botanical data. A confidence band is used in statistical analysis to represent the uncertainty in an estimate of a curve or function based on limited or noisy data. Similarly, a prediction band is used to represent the uncertainty about the value of a new data-point on the curve, but subject ...

  5. Distance sampling - Wikipedia

    en.wikipedia.org/wiki/Distance_sampling

    The half-normal and hazard-rate functions are generally considered to be most likely to represent field data that was collected under well-controlled conditions. Detection probability appearing to increase or remain constant with distance from the transect line may indicate problems with data collection or survey design. [2]

  6. Data collection - Wikipedia

    en.wikipedia.org/wiki/Data_collection

    Data collection or data gathering is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical and social sciences, humanities, [2] and business ...

  7. Partial autocorrelation function - Wikipedia

    en.wikipedia.org/wiki/Partial_autocorrelation...

    Plotting the partial autocorrelation function and drawing the lines of the confidence interval is a common way to analyze the order of an AR model. To evaluate the order, one examines the plot to find the lag after which the partial autocorrelations are all within the confidence interval. This lag is determined to likely be the AR model's order ...

  9. Partially linear model - Wikipedia

    en.wikipedia.org/wiki/Partially_linear_model

    The real-world application of partially linear model was first considered for analyzing data by Engle, Granger, Rice and Weiss in 1986. [2]In their point of view, the relevance between temperature and the consumption of electricity cannot be expressed in a linear model, because there are massive of confounding factors, such as average income, goods price, consumer purchase ability and some ...
