A type of mathematical function that models S-shaped Logistic Function
data, typically used in regression analysis to predict
binary outcomes.
, A statistical measure that indicates how well a regression Coefficient of Determination (r²-value)
model fits the data, with values closer to 1 indicating a
better fit.
A method used to minimize the sum of the squares of the Least Squares Regression (LSR)
residuals, providing the best-fit function for a given data
set.
A data point that significantly deviates from the other Outlier
observations in a dataset, potentially skewing the results
of statistical analyses.
A measure of how a dependent variable changes with Average Rate of Change
respect to an independent variable over a specified
interval.
The rate of change of a dependent variable with respect Instantaneous Rate of Change
to an independent variable at a specific point in time.
A mathematical formula used to calculate the rate of Slope Formula
change between two points, typically represented as the
rise over run.
The variable being measured or predicted in a function, Dependent Variable
which depends on the value of the independent variable.
The variable that is manipulated or controlled in an Independent Variable
experiment to observe its effect on the dependent
variable.
A visual representation of the magnitude of change, Steepness of Rate of Change
where a steeper slope indicates a greater rate of change.
The best possible outcome or decision based on the Optimal Solution
analysis of rates of change over time or at specific points.
In a logistic function, this indicates the rate at which the Exponent
function increases or decreases.
A property of a graph that describes its curvature; it can Concavity
be concave up (shaped like a cup) or concave down
(shaped like a cap).
The point on a graph where the concavity changes, Inflection Point
indicating a shift in the rate of growth or decline.
A line that a graph approaches but never touches, Asymptote
representing a limit to the function's value.
