QUANTITATIVE METHODS:  SOUND BYTE 2
三百字读后感>5色吧Effective Annual Rate:
EAR = (1 + r )m  - 1.0  Future Value:
FV = PV (1 + r)n
Prent Value:

⎢⎢⎢⎢⎣⎡+−r r N )1(11=  PMT(PVIFA r,n )
Future Value of Annuity Due:
FV annuity due = PMT(FVIFA r,n )(1+r)
Prent Value of an Annuity Due:
PV annuity due = PMT(PVIFA r,n )(1+r)
Prent Value of Perpetuities:
PV = PMT/i
Holding Period Return:
HPR = (P 1 – P 0 + D 1)/P 0
Bank Discount Yield:
r BD = t x F D 360
Holding Period Yield: HPY = 0

Effective Annual Yield:
EAY = (1 + HPY)365/t - 1
Money Market Yield:
R MM  = HPY (360/t)
Arithmetic Mean:
μ = Σ X / N, X  = Σ X / n
Weighted Mean:
X w  = Σ w i  × X i
Geometric Mean Return:
R G = [ Π (1 + r t ) ] - 1  = [ Π R t ) ]1/T  - 1
Harmonic Mean:
X H  = 1 / [ { Σ  (1 / X ) } / n ] = n / Σ (1/X
Variance for a Population:
σ2 = ()N X 2∑μ−
Standard Deviation for a Population:
σ = √variance = (variance)1/2
Variance for a Sample:
s 2 = ()1n X X 2−−∑
Standard Deviation for a Sample:

Joint Probability:
P(AB) = P(A ⏐B) ×  P(B)
Total Probability Rule:
P(A) = P(A ⏐S) P(S) + P(A ⏐S C ) P(S C )
Total Probability Rule for Expected Value:
E(X) = E(X ⏐S) P(S) + E(X ⏐S ) P(S )

i i i x p  Covariance:
Cov (R i,R j ) = Σ [ (R i  – E(R i )) (R j  – E(R j )) P(S) ]
Correlation:
ρ(R i,R j ) = Corr(R i,R j ) =  Cov(R i,R j ) / σ(R i ) σ(R j )
Calculating Covariances from Correlations:
Cov(R i,R j ) = Corr(R i,R j) σ(R i ) σ(R j )
Joint Probability Function:
Cov (R i,R j ) = Σ Σ  P(R i,R j ) [R i  - E(R i )]  [(R j  - E(R j )]

ECONOMICS:  SOUND BYTE 3
Price Elasticity of Demand:
price in  change  %demanded
quantity in  change  %demand  of  elasticity  price =食品供货合同
Cross Elasticity of Demand:
complement  or  substitute  of  price  in  change  %demanded
quantity  in  change  %demand  of  elasticity  cross =
Income Elasticity of Demand:阿拉伯大写
income  in  change  %demanded
quantity  in  demand  of  elasticity  income =

quantity  in  supply  of  elasticity =
Economic Profit:
= Total Revenues — (Opportunity costs)
= Total Revenues — Total Explicit Costs — Total Implicit Costs
CPI : CPI basket price at current prices    × 100
CPI basket price at ba period prices
Inflation Rate :

Money Multiplier:
(1 + c) / (r + c)
M:
[(1 + c) / (r + c)] × B
Inflation:
[(Ending price level - Beginning price level)] / Beginning price level
