developing countries. Since empowerment is considered a multidimensional concept‚ it is determined by many socio-economic factors and cultural norms. In this paper‚ an attempt is made to explore the possible determinants of women empowerment using regression analysis based on primary data from a district of Southern Punjab. Considering its multidimensional nature and aspects‚ a cumulative index for women empowerment is constructed using four indices i.e. personal autonomy‚ family decision making‚ domestic

the conventional t and F tests are invalid. (c) If a regression model is mis-specified (e.g.‚ an important variable is omitted)‚ the OLS residuals will show a distinct pattern. (d) If a regressor that has nonconstant variance is (incorrectly) omitted from a model‚ the (OLS) residuals will be heteroskedastic. 2. In a regression of average wages‚ (W ‚ in Rands) on the number of employees (N ) for a random sample of 30 firms‚ the following regression results were obtained (t-statistics in parentheses):

The cell_subs will be become the dependent variable for the forecast in the regression model. Then‚ we could look them at the variable View in the SPSS. At that time‚ we could find the column Missing and enter the Discrete missing values to be 0. After then‚ we turned back to the data view. We could find that there were 196 cases
