If anyone knows what this is, and .

1.093

Step-by-step explanation:

A "sine regression model" is a model of a sine function with 4 different parameters normally named as: and 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:

The parameters   and are associated with different geometric characteristics of the modeling function. For example,   is associated with the function's amplitude,   with the function's period via the relationship: , with the function's horizontal shift via the relationship: to the right if is a negative number, and to the left if c is a positive number. and with the function's vertical shift.

So looking at your functional expression,

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.
