How to conduct path analysis?

Path analysis is a graphical representation of multiple regression models. In this analysis, the graphs represent the relationship between dependent and independent variables with the help of square and arrows. These graphs show the causation between different variables of a regression model. Read more »

How to conduct survival analysis?

Survival analysis is a method under predictive modeling where the dependent variable is time. Therefore, it involves time-to-event prediction modeling. The methodology is that the outcome variable is time until the occurrence of a certain event. The response of the event is known as the survival time, failure time or event time. Read more »

How to perform nonlinear regression?

Regression analysis is a statistical tool to study the relationship between variables. These variables are the outcome variable and one or more exposure variables. In other words, regression analysis is an equation which predicts a response from the value of a certain predictor. In a linear regression analysis model the regression function µY(X1…….Xk) is a linear function of the unknown parameters. Read more »

How to perform and apply Monte Carlo simulation?

Monte Carlo simulation is an extension of statistical analysis where simulated data is produced. This method uses repeated sampling techniques to generate simulated data. For instance, a regression model analyzes the effect of independent variables X1 and X2 on dependent variable Y. Read more »
