st: on counting and fractions in stata

Dear all,
I face the following problem in Stata:
I have a series of daily observations on a given variable and I also have one estimate of this variable that serves as a threshold.
I would like to estimate how many times this threshold is exceeded by comparing the value of this estimate with the available data on daily observations. Is it possible to estimate fractions in Stata in this particular way?
Below is a simple example:
series estimate: 3.1
1.2
2.1
3.2
1.01
Given this data,I would like to get the following estimates (comments in brackets):
count:1 (threshold is exceeded only once)
fraction: 1/4=0.25 (one out of 4 cases)
Many thanks in advance.
Rado
