Computes weights from propensity estimates using the (1 - pi_i)/pi_i formula introduced in Schonlau and Couper (2017).

propensities |
A vector with the propensities associated to the elements of the convenience sample. |
The function takes the vector of propensities π(x) and calculates the weights to be applied in the Hajek estimator using the formula that can be found in Schonlau and Couper (2017). For an individual i, weight is calculated as follows:
w_i = \frac{1 - π_i (x)}{π_i (x)}
A vector with the corresponding weights.
