Housing market analysis method

A method of analysis of statistical data by which a housing market analysis can be made to produce a set of expected value groupings of a total population from information obtained from sample populations, comprising the following steps:

• a) using a median statistic and an average statistic in the sample, calculating a median ratio;
• b) calculating a standard deviation of these median ratios;
• c) dividing the standard deviation of the median ratios by four (4);
• d) using the median of the median ratios, establish groupings by moving in each direction from this median of the median ratios by the amount determined in step (c), these groupings being the ratio probability density distribution;
• e) combining the ratio probability density distribution (d) for the groupings where more than one median ratio is involved, by inspection and selection of a probability for a specific grouping so that the sum the of the probabilities selected total 50 percent for all groupings below the median and 50 percent for all groupings above the median;
• f) using a formula 1−1÷(½ grouping number×½ grouping number) for determining the groupings right of the median above the number observable in the groupings, these new groupings being the ratio probability density distributions to form a set of expected statistics from the sample data;
• g) attaching the ratio probability density distributions to RPDD matching the entry values, median values, average values and total values of the same population;
• h) comparing the expected number of statistics within each number grouping and compare it with the actual number of statistics found in the same grouping and making statistical inferences as to past, present and future real estate needs.
