### Inertia

This study calculates and displays the Inertia study for the Price Data.

Let the Relative Vigor Index Length and Linear Regression Length Inputs be denoted as $$n_{RVI}$$ and $$n_{LR}$$, respectively.

We denote the Inertia of the Price Data at Index $$t$$ for the given Inputs as $$Inertia^{(1)}_t(n_{RVI},(n_{LR})$$. It is a Moving Linear Regression of a Smoothed Relative Vigor Index 2, and we compute it for $$t \geq \max\{(n_{RVI},(n_{LR})\}$$ as follows.

$$Inertia^{(1)}_t(n_{RVI},n_{LR}) = MLR_t\left(\overline{RVI}^{(2)}(n_{RVI}),n_{LR}\right)$$
