  2. Statistical parameter - Wikipedia

    en.wikipedia.org/wiki/Statistical_parameter

    A "parameter" is to a population as a "statistic" is to a sample; that is to say, a parameter describes the true value calculated from the full population (such as the population mean), whereas a statistic is an estimated measurement of the parameter based on a sample (such as the sample mean, which is the mean of gathered data per sampling ...

  3. Gait analysis - Wikipedia

    en.wikipedia.org/wiki/Gait_analysis

    The study encompasses quantification (introduction and analysis of measurable parameters of gaits), as well as interpretation, i.e. drawing various conclusions about the animal (health, age, size, weight, speed etc.) from its gait pattern.

  4. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    All the parameters in the equation are in fact the degrees of freedom of the number of their concepts, and hence, their numbers are subtracted by 1 before insertion into the equation. The equation is: [5] =, where: N is the total number of individuals or units in the study (minus 1)

  5. Sensitivity analysis - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_analysis

    Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be divided and allocated to different sources of uncertainty in its inputs. [1] [2] This involves estimating sensitivity indices that quantify the influence of an input or group of inputs on the output.

  6. Population proportion - Wikipedia

    en.wikipedia.org/wiki/Population_Proportion

    One of the main focuses of study in inferential statistics is determining the "true" value of a parameter. Generally the actual value for a parameter will never be found, unless a census is conducted on the population of study. However, there are statistical methods that can be used to get a reasonable estimation for a parameter.

  7. Linear regression - Wikipedia

    en.wikipedia.org/wiki/Linear_regression

    Parameters in the original model, including , are simple functions of ′ in the standardized model. The standardization of variables does not change their correlations, so { x 1 ′ , x 2 ′ , … , x q ′ } {\displaystyle \{x_{1}',x_{2}',\dots ,x_{q}'\}} is a group of strongly correlated variables in an APC arrangement and they are not ...

  8. Hazard and operability study - Wikipedia

    en.wikipedia.org/wiki/Hazard_and_operability_study

    Typical parameters are flow (or flowrate), temperature, pressure, level, composition, etc. The IEC standard notes guidewords should be chosen that are appropriate to the study, neither too specific (limiting ideas and discussion) nor too general (allowing loss of focus).

  9. Estimation theory - Wikipedia

    en.wikipedia.org/wiki/Estimation_theory

    Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component. The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data.
