1 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 right parenthesis comma space b subscript 2 space left parenthesis X right parenthesis equals left parenthesis X minus 3 right parenthesis I left parenthesis 3 less or equal than X less or equal than 4 right parenthesis plus I left parenthesis 4 less than X less or equal than 5 right parenthesis 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 = -1? -1 0 1 2
