Retinal detachment occurs when the light-sensing layer inside your eye, the retina, detaches from the underlying pigmented tissue layer that provides it oxygen and nutrients. Retinal detachment can happen spontaneously with no obvious or underlying cause.
Thus, vertical analysis is nothing but the comparative analysis of an economic statement, in which all baseline items on an economic statement are shown as a fraction of a further item.
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity. Aries Dell.
