Exemplo De Cálculo Da Média Móvel


Média móvel Este exemplo ensina como calcular a média móvel de uma série temporal no Excel. Um avearge móvel é usado para suavizar irregularidades (picos e vales) para reconhecer facilmente as tendências. 1. Primeiro, vamos dar uma olhada em nossas séries temporais. 2. Na guia Dados, clique em Análise de dados. Nota: não consigo encontrar o botão Análise de dados Clique aqui para carregar o complemento Analysis ToolPak. 3. Selecione Média móvel e clique em OK. 4. Clique na caixa Intervalo de entrada e selecione o intervalo B2: M2. 5. Clique na caixa Intervalo e digite 6. 6. Clique na caixa Escala de saída e selecione a célula B3. 8. Traçar um gráfico desses valores. Explicação: porque definimos o intervalo para 6, a média móvel é a média dos 5 pontos de dados anteriores e o ponto de dados atual. Como resultado, picos e vales são alisados. O gráfico mostra uma tendência crescente. O Excel não pode calcular a média móvel para os primeiros 5 pontos de dados porque não há suficientes pontos de dados anteriores. 9. Repita os passos 2 a 8 para o intervalo 2 e o intervalo 4. Conclusão: quanto maior o intervalo, mais os picos e os vales são alisados. Quanto menor o intervalo, mais próximas as médias móveis são para os pontos de dados reais. Tornar uma média móvel é um processo de suavização Uma maneira alternativa de resumir os dados passados ​​é calcular a média de sucessivos conjuntos menores de números passados ​​da seguinte maneira. Lembre-se do conjunto de números 9, 8, 9, 12, 9, 12, 11, 7, 13, 9, 11, 10, que foram a quantidade de dólares de 12 fornecedores selecionados aleatoriamente. Vamos definir (M), o tamanho do conjunto menor igual a 3. Então a média dos três primeiros números é: (9 8 9) 3 8.667. Isso é chamado de suavização (ou seja, alguma forma de média). Este processo de suavização é continuado avançando um período e calculando a próxima média de três números, deixando cair o primeiro número. Exemplo de média em movimento A próxima tabela resume o processo, que é referido como Lotação ambulante. A expressão geral para a média móvel é Mt frac cdots X.
