## Setup for independent simple random variables

MATLAB version 5.1 has provisions for multidimensional arrays, which make possible more direct implementation of icalc3 and icalc4.

icalc.m Calculation setup for an independent pair of simple random variables. Input consists of marginal distributions for $X,Y$ , Output is joint distribution and calculating matrices $t,u$ .

% ICALC file icalc.m Calculation setup for independent pair % Version of 5/3/95% Joint calculation setup for independent pair X = input('Enter row matrix of X-values ');Y = input('Enter row matrix of Y-values '); PX = input('Enter X probabilities ');PY = input('Enter Y probabilities '); [a,b]= meshgrid(PX,fliplr(PY)); P = a.*b; % Matrix of joint independent probabilities[t,u] = meshgrid(X,fliplr(Y)); % t, u matrices for joint calculationsdisp(' Use array operations on matrices X, Y, PX, PY, t, u, and P')

What is demand
the amount of a good that buyers are willing and able to purchase
Asit
what is population
The people living within a political or geographical boundary.
Ziyodilla
what happens to price and quantity when demand curves shift to the right
price level goes up. quantity demand increases
Asit
example- inferior goods
Asit
demand law
Athony
Its states that higher the price the of the commodity, and lower the quantity demanded
Kosiso
I am confused but quantity demand will increase.
Asit
No. That's the law of supply
Kosiso
what happens to price and quantity when supply curve shifts left?
price level will increase
Asit
quantity demand will decrease
Asit
what is inflation
inflation is a general and ongoing rise in the level of prices in an entire economy.
cynthia
is the pasistance increase in the price of a country economy
Liyu
kk
Duppy
yes
how does inflation affects the economy of a country? what is deflation?
Augustine
deflation can simply be define as the persistence decrease in price of a countrys economy
Liyu
the revenge of malthus relates "revenge" with "commodity prices". collect data for 3 commodoties and check their price evolution
what is elasticity
Elasticity is an economics concept that measures responsiveness of one variable to changes in another variable.
cynthia
right
Augustine
wooow!!
cynthia
Computer software represents

Hey what are you trying to mean?
Kenyana
what is Asset
MUBARAK
like a banana
Ahmed
demand is the process whereby consumers are willing and able to purchase a particular product at various price over a given period of time

what is financial market
what is demand
Demand is an economic principle referring to a consumer's desire to purchase goods and services and willingness to pay a price for a specific good or service.
Ali
explain any three exceptions to the law of demand
