Var I 0

Var I 0. var The var declaration is similar to let Most of the time we can replace let by var or viceversa and expect things to work var message = “Hi” alert( message) But internally var is a very different beast that originates from very old times It’s generally not used in modern scripts but still lurks in the old ones.

PDF fileyi = 0 + 1xi+ “i where Var(“i) = x2 i ˙ 2 We can transform this into a regular least squares problem by taking y0 i = yi xi x0 i = 1 xi “0 i = “i xi Then the model is y0 i = 1 + 0x 0 i+ “0 i where Var(“0 i) = ˙2 76 Weighted Least Squares as a Transformation The residual sum of squares for the transformed model is S1( 0 1) = Xn i=1 (y0 i 1 0x 0 i) 2 = Xn i=1 yi xi 1 0 1 xi!2 = Xn i=1 1.

JavaScript for Loop

Statement 1 sets a variable before the loop starts (let i = 0) Statement 2 defines the condition for the loop to run (i must be less than 5) Statement 3 increases a value (i++) each time the code block in the loop has been executed Statement 1 Normally you will use statement 1 to initialize the variable used in the loop (let i = 0).
