Question

If anyone knows what this is, please and thanks.

Answer 1

1.093

Explanation:

A "sine regression model" is a model of a sine function with 4 different parameters normally named as:
`a, b, c,` and
`d.` that is returned to the user after trying to fit a set of numerical values using a sinusoidal function.

The model and parameters are normally defined as follows:

`y=a*sin(bx+c) + d`

The parameters
`a, b, c,` and
`d` are associated with different geometric characteristics of the modeling function. For example,
`a` is associated with the function's amplitude,
`b` with the function's period via the relationship:
`period=(2\pi )/(b)`,
`c` with the function's horizontal shift via the relationship:
`H_s= (|c|)/(b)` to the right if
`c` is a negative number, and to the left if
`c`c is a positive number. and
`d` with the function's vertical shift.

So looking at your functional expression,

`c` is represented in absolute value by the number 1.093 that appears in the argument of the sine function,and indicates that there is a shift to the right from the standard sine function.
