20090601 Drawing a Linear Regre ss ion Graph Linear regression uses the method of least squares to determine the equation that best fits your data points, and returns values for the slope and y -intercept. The graphic representation of this relationship is a linear regression graph.
20060301 Drawing a Med-Med Graph When you suspect that the data contains extreme values, you should use the Med-Med graph (which is based on medians) in place of the linear regression graph. Med-Med graph is similar to the linear regression graph, but it also minimizes the effects of extreme values.
20060301 Drawing Quadratic, Cubic, and Quar tic Regre ss ion Graph s You can draw a quadratic, cubic, or quartic regression graph based on the plotted points. These graphs use the method of least squares to draw a curve that passes the vicinity of as many data points as possible.

20060301 Drawing a Logarithmic Regre ss ion Graph Logarithmic regression expresses y as a logarithmic function of x . The normal logarithmic regression formula is y = a + b · ln( x ). If we say that X = ln( x ), then this formula corresponds to the linear regression formula y = a + b ·X.
20060301 Drawing an Exponential Regre ss ion Graph ( y = a · e b · x ) Exponential regression can be used when y is proportional to the exponential function of x . The normal exponential regression formula is y = a · e b · x . If we obtain the logarithms of both sides, we get ln( y ) = ln( a ) + b · x .
20060301 Drawing an Exponential Regre ss ion Graph ( y = a · b x ) Exponential regression can be used when y is proportional to the exponential function of x . The normal exponential regression formula in this case is y = a · b x . If we take the natural logarithms of both sides, we get ln( y ) = ln( a ) + (ln( b )) · x .
20060301 Drawing a P ower Regre ss ion Graph ( y = a · x b ) Power regression can be used when y is proportional to the power of x . The normal power regression formula is y = a · x b . If we obtain the logarithms of both sides, we get ln( y ) = ln( a ) + b · ln( x ).
20060301 The following is the sinusoidal regression model formula. y = a ·sin( b · x + c ) + d Tip • Make sure that “Radian” is selected for the [Angle] setting on the Basic Format dialog box (page 1-9-4) before drawing a sinusoidal regression graph.

20060301 8-3-11 Editing Figures A highlighted check box indicates the measurement is fixed (constrained). I Fixing a Mea s urement of a Figure By “fixing a measurement” we mean that a constraint is placed on the figure. For example, if we fix (constrain) a point to a circle and move the circle, the point will also move.

20060301 I Example 2 Suppose you were offered the investment in Example 1 at a cost of $1,000. What is the net present value (NPV) of the investment? What is the internal rate of return (IRR)? Note • When performing the calculations for Example 2, you need to enter the cost, as a negative value (–1000), in cell 1 of list1 in the stat editor.
20060301 S IRR IRR is calculated using Newton’s Method. In this formula, NPV = 0, and the value of IRR is equivalent to i s 100. It should be noted, however, that minute fractional values tend to accumulate during the subsequent calculations performed automatically by the calculator, so NPV never actually reaches exactly zero.
20060301 15-5-1 Amor tization 15-5 Amor tization Amortization lets you calculate the interest and principal portions of a payment or payments. Amor tization Field s The following fields appear on the Amortization calculation page.

20060301 15-9-1 Depreciation 15-9 Depreciation Depreciation lets you calculate the amount that a business expense can be offset by income (depreciated) over a given year. You can use a Depreciation page to calculate depreciation using one of four methods: straight-line, fixed-percentage, sum-of-the-years’-digits, or declining-balance.
20060301 15-9-2 Depreciation Tip • At the end of the useful life the value of the computer will be 0, so we enter 0 in the FV field. I Example 1 Use the sum-of-the-years’-digits method ([SYD]) to calculate the first year ( j = 1) of depreciation on an $12,000 (PV) computer, with a useful life (N) of five years.
20060301 I Example 2 Now calculate the depreciation amount ([SYD]) for the second year ( j = 2). Note • You can also tap [SL] to calculate depreciation using straight-line method, [FP] using fixed- percentage method, or [DB] using declining-balance method.

20060301 15-10-2 Bond Calculation I Example 1 You want to purchase a semiannual (Compounding Frequency = Semi-annual) corporate bond that matures on 12/15/2006 (d2) to settle on 6/1/2004 (d1). The bond is based on the 30/360 day-count method (Days in Year = 360 days) with a coupon rate (CPN) of 3%.
20060301 15-10-3 Bond Calculation I Example 2 For the same type of bond described in Example 1, calculate the price on the bond (PRC) based on a specific number of coupon payments (Term). • Before performing the calculation, you should use the [Format] tab to change the [Bond Interval] setting to “Term”, or tap “Date” in the status bar.
20060301 PRC : price per $100 of face value CPN : coupon rate (%) YLD : annual yield (%) A : accrued days M : number of coupon payments per year (1 = Annual, 2 = Semi-annual) N : number of coupon payments until maturity ( n is used when “Term” is specified for [Bond Interval] in the [Format] tab.
20060301 Bond Interval Setting: Term S Annual Yield (YLD) YLD is calculated using Newton’s Method. Note • The Financial application performs annual yield (YLD) calculations using Newton’s Method, which produces approximate values whose precision can be affected by various calculation conditions.
20060301 15-11-1 Break-Ev en P oint 15-11 Break-Even P oint Break-Even Point lets you calculate the amount you must sell to break even or to obtain a specified profit, as well as the profit or loss on particular sales.

Note • You need to calculate the break-even point sales quantity ([QBE]) before you will be able to calculate the break-even sales amount ([SBE]).
20060301 I Example 2 What is the break-even point sales amount ([SBE]) and sales quantity ([QBE]) to attain a profit ratio ([r%]) of 40%? • For this example, use the [Format] tab to change the [Profit Amount/Ratio] setting to “Ratio ( r %)” or tap “PRF” in the status bar to change it to “ r %”.
