Modeling of volatility of interest and treasury bill rates using arch / garch family models and their effect on pension fund
(University of Nairobi, 2016-12)The interest rate and Treasury bill rates were converted into simple returns and modeled by use of ARCH and GARCH (1, 1) models. The GARCH (1,1) was preferred because it allows many parameters and considers conditional ... -
Modeling of Wholesale Prices for Selected Vegetables Using Time Series Models in Kenya
(University of Nairobi, 2014-07)Price forecasting is more sensitive with vegetable crops due to their highly nature of perishability and seasonality and is often used to make better-informed decisions and to manage price risk. Further, to improve ... -
Modeling Online Auction Prices And Their Dynamics Using Functional Data Analysis
