# Supervised Numeric-Value Prediction Task

(Redirected from regression analysis)

A supervised numeric-value prediction task is a data-driven point estimation task that is a supervised estimation task.

**Context:****input:**a Numerically Labeled Training Dataset.**output:**an Predicted Numeric Value.- optional output: a Trained Estimation Function.

**Performance Metric**: Numeric-Value Prediction Performance Metric, such as RMSE.- It can be solved by a Supervised Numeric Prediction System (that implements a supervised point estimation algorithm).
- It can range from being a Supervised Model-based Numeric Prediction Task (such as linear regression) to being a Supervised Instance-based Point Estimation Task (such as k-nearest regression).
- It can range from being a Fully-Supervised Regression Task to being a Semi-Supervised Regression Task.
- It can range from being a Univariate Regression Task to being a Multivariate Regression Task (with more than one dependent variable).

**Example(s):**- predict the orbit of stellar objects based on past history (like Gauss did on ~1805).
- predict Boston housings sales price based on a (Harrison & Rubinfeld, 1978) dataset, such as sklearn's Boston dataset.
- a (Fanaee-T & Gama, 2014) Prediction Task.
- …
