  2. Panel data - Wikipedia

    en.wikipedia.org/wiki/Panel_data

    Panel data. In statistics and econometrics, panel data and longitudinal data[ 1][ 2] are both multi-dimensional data involving measurements over time. Panel data is a subset of longitudinal data where observations are for the same subjects each time. Time series and cross-sectional data can be thought of as special cases of panel data that are ...

  3. Arellano–Bond estimator - Wikipedia

    en.wikipedia.org/wiki/Arellano–Bond_estimator

    Regression analysis. In econometrics, the Arellano–Bond estimator is a generalized method of moments estimator used to estimate dynamic models of panel data. It was proposed in 1991 by Manuel Arellano and Stephen Bond, [ 1] based on the earlier work by Alok Bhargava and John Denis Sargan in 1983, for addressing certain endogeneity problems ...

  4. Panel analysis - Wikipedia

    en.wikipedia.org/wiki/Panel_analysis

    Panel analysis. Panel ( data) analysis is a statistical method, widely used in social science, epidemiology, and econometrics to analyze two-dimensional (typically cross sectional and longitudinal) panel data. [ 1] The data are usually collected over time and over the same individuals and then a regression is run over these two dimensions.

  5. Differential scanning calorimetry - Wikipedia

    en.wikipedia.org/wiki/Differential_scanning...

    Differential scanning calorimetry ( DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. [ 1] Both the sample and reference are maintained at nearly the same temperature throughout the experiment.

  6. Time series - Wikipedia

    en.wikipedia.org/wiki/Time_series

    Time series. In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily ...

  7. Global surface temperature - Wikipedia

    en.wikipedia.org/wiki/Global_surface_temperature

    Global surface temperature (GST) is the average temperature of Earth 's surface. It is determined nowadays by measuring the temperatures over the ocean and land, and then calculating a weighted average. The temperature over the ocean is called the sea surface temperature. The temperature over land is called the surface air temperature.

  8. Geologic temperature record - Wikipedia

    en.wikipedia.org/wiki/Geologic_temperature_record

    Geologic temperature record. The geologic temperature record are changes in Earth 's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.

  9. Multidimensional panel data - Wikipedia

    en.wikipedia.org/wiki/Multidimensional_panel_data

    Multidimensional panel data. In econometrics, a multidimensional panel data is data of a phenomenon observed over three or more dimensions. This comes in contrast with panel data, observed over two dimensions (typically, time and cross-sections ). An example is a data set containing forecasts of one or multiple macroeconomic variables produced ...
