Yuki answered with a knowing look: “Not surprising you are doing statistics. You like quantitative data.

In fact we have already seen the Sample Statistics that we will use to estimate the Parameters A political scientist wants to use regression analysis to build a model for support for Fianna Fail. Two variables considered as possibly effecting support for Fianna Fail are whether one is middle class or whether one is a farmer. These variables are described below: y = Fianna Fail Support x1 Regression analysis is widely used for prediction (including forecasting of timeseries data). Use of regression analysis for prediction has substantial overlap with the field of machine learning. Regression analysis is also used to understand which among the independent variables are related to the dependent variable, and to explore the forms of these relationships. In restricted circumstances
