Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method (sometimes known as ordinary least squares, or OLS) to arrive at the geometric equation for the line, either through manual calculations or by using software.

“Prediction” refers to the output of an algorithm after it has been trained on a historical dataset and applied to new data when forecasting the likelihood of a particular outcome, such as whether or not a customer will churn in 30 days. The algorithm will generate probable values for an unknown variable for each record in the new data, allowing the model builder to identify what that value will most likely be.

The focus of supervised learning revolves around the input and output variables using an algorithm to predict the outcome. If a new input variable comes into the picture. The linear regression algorithm in machine learning is a supervised learning technique to approximate the mapping function to get the best predictions.Read more on this free link

In social science research, it is rare that we would only want to include one explanatory variable in our regression analysis. It is more likely that we would want to investigate the effect that two or more factors have on an outcome, such as confidence in the police. This might be because variables may measure the same thing or have similar relationships – we want to know what the relationship is while also controlling for the influence of other variables.

As an investor, wouldn’t it be nice to know that your portfolio both limits your risk and maximizes return? Ideally, it will do just that. The efficient frontier is a set of investment portfolios that maximizes returns while minimizing risk. Read more on this free link
