+### 1\. **Linear Regression**
+
+* **Simple Linear Regression**
+  * **Applications**: Relationship between one independent and one dependent variable, e.g., predicting income based on education level.
+  * **Requirements**: Linear relationship, normal distribution of errors, homoscedasticity (constant variance of errors), independence of errors.
+* **Multiple Linear Regression**
+  * **Applications**: Relationship between multiple independent variables and one dependent variable, e.g., predicting house prices based on location, size, and age.
+  * **Requirements**: Same as simple linear regression but for multiple independent variables.
+
+### 2\. **Logistic Regression**
+
+* **Binary Logistic Regression**
+  * **Applications**: Predicting a binary outcome, e.g., disease prediction (disease/no disease).
+  * **Requirements**: Dependent variable is binary, independent variables can be continuous or categorical, no perfect multicollinearity.
+* **Multinomial Logistic Regression**
+  * **Applications**: Predicting a categorical variable with more than two non-ordered categories, e.g., choice of transportation method (car, bus, bike).
+  * **Requirements**: Dependent variable has more than two categories that are not ordered.
+* **Ordinal Logistic Regression**
+  * **Applications**: Predicting an ordered categorical variable, e.g., satisfaction scale (very dissatisfied to very satisfied).
+  * **Requirements**: Dependent variable is ordinal, proportional odds assumption (effects of independent variables are constant across categories).
+
+### 3\. **Poisson Regression**
+
+* **Applications**: Modeling count data, e.g., number of car accidents per year.
+  * **Requirements**: Dependent variable is a count variable, events are independent, event rate is constant.
+
+### 4\. **Negative Binomial Regression**
+
+* **Applications**: Modeling over-dispersed count data, e.g., number of emergency room visits by chronically ill patients.
+  * **Requirements**: Same as Poisson regression, but variance greater than the mean.
+
+### 5\. **Quantile Regression**
+
+* **Applications**: Analyzing the distribution of a dependent variable, e.g., wage distribution at different quantiles (median, upper quartile).
+  * **Requirements**: No specific assumptions about the distribution of errors, robust to outliers.
+
+### 6\. **Ridge Regression**
+
+* **Applications**: Dealing with multicollinearity in linear regression, e.g., predicting marketing expenditures.
+  * **Requirements**: Independent variables are highly correlated.
+
+### 7\. **Lasso Regression**
+
+* **Applications**: Variable selection and regularization, e.g., genomic data analysis.
+  * **Requirements**: Same as ridge regression but sets some coefficients to zero.
+
+### 8\. **Elastic Net Regression**
+
+* **Applications**: Combining advantages of ridge and lasso, e.g., complex economic models.
+  * **Requirements**: Data exhibits both high multicollinearity and the need for variable selection.
+
+### 9\. **Probit Regression**
+
+* **Applications**: Binary classification problems, e.g., creditworthiness evaluation.
+  * **Requirements**: Dependent variable is binary, uses normal distribution.
+
+### 10\. **Tobit Regression**
+
+* **Applications**: Censored data, e.g., income data with upper and lower limits.
+  * **Requirements**: Dependent variable is censored, linear model above and below censoring thresholds.
+
+### 11\. **Cox Regression**
+
+* **Applications**: Survival analysis, e.g., time until event occurrence (death, relapse).
+  * **Requirements**: Time to event data, independent variables can be continuous or categorical, proportional hazards.
+
+### 12\. **Polynomial Regression**
+
+* **Applications**: Modeling non-linear relationships, e.g., growth processes.
+  * **Requirements**: Relationship between independent and dependent variables is polynomial.
+
+### 13\. **Spline Regression**
+
+* **Applications**: More flexible fits than linear models, e.g., time series analysis.
+  * **Requirements**: Data exhibits non-linear trends.
+
+### 14\. **Log-Log Regression**
+
+* **Applications**: Modeling multiplicative relationships, e.g., economies of scale in production.
+  * **Requirements**: Both variables are positive and can be logged.
+
+### 15\. **Generalized Linear Models (GLM)**
+
+* **Applications**: Various distributions of the dependent variable, e.g., binomial, Poisson, gamma distributions.
+  * **Requirements**: Dependent variable follows one of the distributions in the GLM framework.
+
+### 16\. **Nonlinear Regression**
+
+* **Applications**: Non-linear relationships between variables, e.g., pharmacokinetics.
+  * **Requirements**: The relationship between independent and dependent variables is non-linear and known.
+
+These regression types offer various tools for analysis and prediction based on the nature of the data and the underlying relationships between variables.
