Least Square and Residual Analysis in Data Science

66.2k

  • Least Square Method: The Least Square method is a form of regression analysis that calculates a linear combination of independent variables (X) to minimize the sum squared residuals (S).
  • Residual Analysis: Residual analysis is a statistical technique for finding patterns in data, which can be used to identify outliers and other important features.

The Least Squares Regression Line is the line that minimises the squared sum of residuals. By subtracting y from y, the residual is the vertical distance between the observed and predicted points.

Least square analysis is used to find the best fit of a function to its data set. It is a linear equation that minimizes the squared distance between the observed and fitted values.

There are many ways in which AI can be used to help data science projects:

  • Generating insights: AI can be used to generate insights that might not have been reached by human scientists.
  • Automating tasks: Data science projects often require a lot of repetitive work and the use of AI tools can automate this process.
  • Generating data sets: Data science projects often require a lot of data and the use of AI tools can generate these data sets at scale.
  • Data augmentation: Data science projects often require additional information about the dataset, such as demographics, geographies, etc.,

The following are some of the advantages of this method: Many statistical software packages that do not offer maximum likelihood estimations may include non-linear least squares software. It has a broader use than maximal likelihood.

The content and teaching style is excellent. But there is slight issue is that video quality is kind of poor the dashboard is blur on 720mp on PC.
