how to use estimated parameters to calculate probabilities using a density function?
I used a qqplot to find my data is from the t distribution.  Then i used the fitdistr function to estimate the parameters of the model for the t distribution and i got a df=4, scale=181.28, and location=10.68.  I then want to calculate the probability that X <= -1 using the parameters of the model and my data.  How should I approach this.
