- Linear regression can be applied to all those data sets where variables have a linear relationship. Businesses can use the linear regression algorithm is their sales data. Suppose you are a business that is planning to launch a new product. But, you are not really sure at what price you should sell this product.
- regression models for prediction purposes in various disciplines. Due to the nature of linear relationship in the parameters, regression models may not provide accurate predictions in some complex situations such as non linear data and extreme values data. As regression modelsneed to fulfill the regression assumptionsand multiple co-linearity

- Further, it's common to fit a log-link with the gamma GLM (it's relatively more rare to use the natural link). What makes it slightly different from fitting a normal linear model to the logs of the data is that on the log scale the gamma is left skew to varying degrees while the normal (the log of a lognormal) is symmetric.

- intervals. Diehr et al. (1999) recommend OLS only when the goal is future cost prediction. Lognormal Models: Aitchison and Brown (1957) give historical background on the use of this model, commonly applied to make skewed data 'look more normal' whereupon linear regression tech-niques can be applied with more conﬁdence.
- Cost-sensitive learning is a subfield of machine learning that takes the costs of prediction errors (and potentially other costs) into account when training a machine learning model. It is a field of study that is closely related to the field of imbalanced learning that is concerned with classification on datasets with a skewed class distribution.
- Oct 14, 2020 · Regression - Automobile Price Prediction (Basic) Predict car prices using linear regression. Regression - Automobile Price Prediction (Advanced) Predict car prices using decision forest and boosted decision tree regressors. Compare models to find the best algorithm.
- Logistic Regression: The linear regression fits a line and is used to predict a continuous value. For example, we estimate the price of a house using linear regression. However, the logistic regression fits an s-shaped function and predicts whether something is true or false. It is mainly used in binary classification problems.
