1.6.1. Data Aaalysis<br />

Data collected from various sources were analysed by means <strong>of</strong> statisti-<br />

cal techniques such as averages, percentages, compound growth rate, regres·<br />

sioo and correlation.<br />

Compound growth rates were worked out by fiuing exponential function<br />

Y = AB' to the cropped acreage, production and productivity data for India,<br />

<strong>Kerala</strong>, other major producing states, Wynad and Ernakulam districts. Corn·<br />

pound growth rates were also estimated for the export <strong>of</strong> ginger and spices<br />

from India. <strong>The</strong> exponential function was converted into the linear form using<br />

logarithms. That is:<br />

Log Y = Log A + t Log B<br />

y = a + bt + e<br />

Where log Y is <strong>of</strong> the log <strong>of</strong> dependent variable (acreage, production,<br />

productivity or export) and 't' is independent time variable.<br />

Nerlovian model was used to analyse acreage response <strong>of</strong> ginger farm-<br />

crs. Nerlove defined a long run acreage response function in the following<br />

manner:<br />

Where At = desired long run acreage<br />

P t -, = lagged price, and<br />

v = error term<br />

I<br />

ao and a, are the intercept and slope <strong>of</strong> the function.<br />
