Question

if regression coeefficients byx=0 and bxy=0 then correlation coefficient r will be ​

Answer 1

If regression coefficients byx=0 and bxy=0 then correlation coefficient r will be ​negative.

Linear regression:

• Linear reversion reasoning is used to predict the profit of a changing established the advantage of another variable.
• The changing you be going to think is named the dependent changing.
• The changing you are utilizing to predict the added changing's advantage is named the independent changing.
• This form of study estimates the coefficients of the undeviating equating, involving individual or more liberated variables that best call the value of the helpless changeable.
• Linear reversion fits a direct route or surface that minimizes the discrepancies 'tween forecasted and real product values. There are plain undeviating reversion calculators that use a “least squares” arrangement to find high-quality-fit line for a set of mated data.
• Have to analyse before estimate the profit of X (helpless changeable) from Y (independent changing).
