Prediction units The errors in predicting hurricanetracks (examined in this chapter) were given in nauticalmiles. An ordinary mile is 0.86898 nautical miles. Mostpeople living on the Gulf Coast of the United Stateswould prefer to know the prediction errors in milesrather than nautical miles. Explain why converting theerrors to miles would not change the correlation betweenPrediction Error and Year.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
