Determination of the lag length of an autoregressive process is one of the most difficult parts of ARIMA modeling. Various lag length selection criteria (Akaike Information Criterion, Schwarz Information Criterion, Hannan-Quinn Criterion, Final Prediction Error, Corrected version of AIC) have...

Business as usual will not be enough to tackle the critical issue of having sustainable increase in agricultural productivity and food security, which Pakistan is facing at the moment and in future it can become very alarming. Innovative approach is essential for food policy, for enhancing...

This study investigates the determinants of food insecurity for both general and farmer households. It is based on Pakistan Social and Living standard Measurement (PSLM) 2007-08 survey conducted by the Federal Bureau of Statistics, Pakistan. After having descriptive analysis of the important...
