My questions are: 1) What do the +/- values behind accuracy, precision and recall mean? Like the 14.58% in accuracy: 77.50% +/- 14.58% Is this the confidence interval, i.e. in which interval the real value with respect to the estimated value can lie? If so, what is the confidence level used here? WebRegression is a technique used for numerical prediction and it is a statistical measure that attempts to determine the strength of the relationship between one dependent variable ( i.e. the label attribute) and a series of other changing variables known as independent variables (regular attributes). the bad guys movie merch
