2 Suppose we fit a curve with basis functions b subscript 1 space left parenthesis X right parenthesis equals I left parenthesis 0 less or equal than X less or equal than 2 right parenthesis minus left parenthesis X minus 1 right parenthesis I left parenthesis 1 less or equal than X less or equal than 2 We fit the linear regression model Y=0+1 b1 (X)+2 b2 (X)+ and obtain coefficient estimates 0=1, 1=1, 2=3. What is the value of Y when X = 0? -1 0 1 2
