In this question, the objective is to determine the correct conclusion based on the statement, the line of regression perfectly fits on the training data.
00:11
So let us understand what does it mean by perfectly and then we can write fits.
00:18
So it can be written as such and then it will be here on training.
00:24
Now it is going to be data.
00:27
So this statement or this clause.
00:30
Implies that the regression line passes exactly through all the training data points.
00:37
In other words, predicted value, so it will be predicted and then it is going to be values, match the actual values.
00:47
So it will be match and now we can write the actual values.
00:53
So it is written over here as actual and then it will be values for all points on the training set or in the training set.
01:04
So let us check the options one by one and in the first option it is saying that error on training data will be zero.
01:13
So this is true because the regression line perfectly fits the training data which means there is no difference between the predicted value and actual values.
01:23
So error will be zero.
01:25
Now let us check the same...
