Simple linear regression
In simple linear regression, we try to predict one variable in terms of a second variable called a predictor variable. The variable we are trying to predict is called the dependent variable and is denoted by y, and the independent variable is denoted by x. In simple linear regression, we assume a linear relationship between the dependent attribute and predictor attribute.
First we need to plot the data to understand the linear relationship between the dependent variable and independent variable. Here our, data consists of two variables:
YPrice
: Dependent variableXPrice
: Predictor variable
In this case, we are trying to predict Yprice
in terms of XPrice
. StockXprice
is the independent variable and StockYprice
is the dependent variable. For every element of StockXprice
, there is an element of StockYprice
, which implies one-to-one mapping between elements of StockXprice
and StockYprice
.
