In plain terms
The intercept anchors the model coordinate system even if no pivot exists at index zero.
Technical
intercept_log = a* in z_hat(t)=a*+b*t; exponentiating gives the line's price at index zero under the model.
Scope
An intercept is a coordinate parameter, not an observed support or resistance value.
Examples
- A reviewer computes Trendline Intercept on a small deterministic fixture and checks timing, units, and boundary behavior before publication.
Common misconceptions
- An intercept is a coordinate parameter, not an observed support or resistance value.
Concept relationships
Where this concept is used
Evidence and governance
- Linear Least Squares Regression NIST/SEMATECH · official standard
Supports: preferred label, short definition, technical definition, formula
Limits: A fitted line remains descriptive and is not evidence of a future price path.
- sklearn.linear_model.RANSACRegressor scikit-learn · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: This package enumerates every two-point hypothesis for small pivot sets instead of using random sampling.
- numpy.log NumPy · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: A log transform requires positive finite prices and does not by itself define a financial level.
- numpy.polyfit NumPy · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: The glossary freezes its own log-space OLS contract, diagnostics, and tie rules.
