Let's Learn Math Logic

Hye everyone

How your new year

Have you already planned target for 2017???

If not u must set now

Let's learn math 

Small part in Math Logic

Logic

Negation (¬) = not @ it is not the case that…

Example: Emily does not eat nasi lemak

p	¬p
T	F
F	T

Conjuction (^) = and @ sometimes “but”  p^q

Example Emily eat nasi lemak and Frank eats nasi dagang

p	q	p^q
T	T	T
T	F	F
F	T	F
F	F	F

Disconjuction (˅) = or

Example: Emily eats nasi lemak or Frank eat nasi dagang

p	q	p˅q
T	T	T
T	F	T
F	T	T
F	F	F

Implication (→) = “If …then…”   p→q

Example: If Emily eats nasi lemak, then Frank eats nasi dagang

p	q	p→q
T	T	T
T	F	F
F	T	T
F	F	T

Biconditional (↔) : “….if and only if…”  p↔q¬

Example: Emily eats nasi lemak if and only if Frank eats nasi dagang.

p	q	p↔q
T	T	T
T	F	F
F	T	F
F	F	T

Logical Equivalence : The laws of Logic

1) Logically equivalent : ¬¬p

p	¬p	¬¬p
T	F	T
F	T	F

2) Tautology = last answer in truth table must be true

3) Contradiction = last answer in truth table must be false

CONDITIONAL	p→q
CONVERSE	q→p
INVERSE	¬p→¬q
CONTRAPOSITIVE	¬q→¬p

Issue to be considered when formulating quantitative models.

1) Accuracy of forecasts.

• Determining the degree of accuracy of the forecasts remains the top most consideration among the forecasters.

2) Determine the Forecast Horizon.

• Forecast Horizon is time in the future at which the forecasts are required. 

4 Categories of horizon

1) Long term forecasts

• Looks at several year of forecast

2) Medium term forecasts

• 6 months until 2 years

3) Short term forecasts

• 1 month until 6 months 

4) Immediate term forecasts

• Less than one month

Factors to be considered for successful forecasting practices.

1) TimeFrame

• Refer to Forecast Horizon.

2) Choice of technique

• Technique should be selected so that the underlying assumption matches the characteristics of the data. 

3) Cost consideration

• Cost consideration associated with every formulation and development of the forecastin models.
• Example: labour cost, cost of testing computer program.

4) Availability of data

• Long series of data would enable the modeller to obtain accurate and reliable model estimates.

Stages in Forecasting procedure

1) Determination of the purpose and objective forecasting exercise

2) Selection of relevant theory

3) Collection of the data

4) Getting to know your data

5) Initial model estimation

6) Model evaluation and revision

7) Initial forecast presentation

8) Final revision

9) Forecast distribution

10) Establish monitoring system
